With the Pioneer Regional Championship in Atlanta having just recently concluded, there’s been a big emphasis on what decks would emerge as the top dogs in the metagame. Since the recent banning of
Karn, the Great Creator

+1: Until your next turn, up to one target noncreature artifact becomes an artifact creature with power and toughness each equal to its mana value.
−2: You may reveal an artifact card you own from outside the game or choose a face-up artifact card you own in exile. Put that card into your hand.
and
Geological Appraiser


Whenever this Vehicle attacks or blocks, you may draw a card. If you do, discard a card.
Crew 1 (Tap any number of creatures you control with total power 1 or more: This Vehicle becomes an artifact creature until end of turn.)
, many players were curious exactly what archetypes would be the most represented and what decks would overperform.
Unsurprisingly, decks like Rakdos midrange, Izzet Phoenix, and Abzan
Amalia Benavides Aguirre

Whenever you gain life, Amalia Benavides Aguirre explores. Then destroy all other creatures if its power is exactly 20. (To have this creature explore, reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on this creature, then put the card back or put it into your graveyard.)
combo had great tournaments overall. Sometimes in big tournaments like these, though, a unique strategy breaks out. Whenever a cool combo emerges on the big scene, it’s big news. Unfortunately, one of the most intriguing combo decks from the event just barely missed out on day two, so it is very much under the radar.
This deck is a Sultai combo deck built around
Gwenna, Eyes of Gaea

Whenever you cast a creature spell with power 5 or greater, put a +1/+1 counter on Gwenna and untap it.
. There’s a ton going on, as the deck is incredibly unique. This got us thinking: what fun combo decks are underrated that players don’t talk about enough? Today, we are going to cover a wide range of different combos in various formats that perhaps haven’t had their time in the spotlight. Let’s start by looking closer at this Sultai combo deck in more detail.
Sultai Gwenna Combo

This deck has a ton of moving parts, but the primary focus of the deck is to utilize the abilities of Gwenna, Eyes of Gaea. Gwenna can tap for two mana in any color combination to spend on Creatures spells or activated abilities of Creatures. You also get to untap Gwenna if you cast a Creature with power five or greater, and Gwenna gets a +1/+1 counter. With Gwenna and Kinnen, Bonder Prodigy in play, there are multiple combos that can be assembled.
The first combo involves getting
Acererak the Archlich

Whenever Acererak attacks, for each opponent, you create a 2/2 black Zombie creature token unless that player sacrifices a creature of their choice.
into play. Acererak lets you Venture into the Dungeon and gets returned to your hand if you haven’t completed Tomb of Annihilation specifically. With Kinnen and Gwenna in play, Gwenna can tap to cast Acererak by itself. Acererak has five power, so Gwenna will untap. This allows you to keep casting Acererak over and over, generating value by completing every Dungeon and growing Gwenna over time.
Once you add
Agatha’s Soul Cauldron

Creatures you control with +1/+1 counters on them have all activated abilities of all creature cards exiled with Agatha's Soul Cauldron.
{T}: Exile target card from a graveyard. When a creature card is exiled this way, put a +1/+1 counter on target creature you control.
into the mix, there are even more shenanigans to be had. With Kinnen in play, you can actually generate infinite mana by exiling
Sleep-Cursed Faerie

This creature enters tapped with three stun counters on it. (If it would become untapped, remove a stun counter from it instead.)
{1}{U}: Untap this creature.
from your graveyard and putting a +1/+1 counter on Gwenna. Gwenna can tap for three mana total, two of which can be used to untap itself.
Notably, you can also exile both Sleep-Cursed Faerie and Gwenna from the graveyard with Cauldron, and your other Creatures with +1/+1 counters will be able to generate infinite mana as a result. This infinite mana can allow you to activate Kinnan over and over, putting cards like
Atraxa, Grand Unifier

When Atraxa enters, reveal the top ten cards of your library. For each card type, you may put a card of that type from among the revealed cards into your hand. Put the rest on the bottom of your library in a random order. (Artifact, battle, creature, enchantment, instant, land, planeswalker, and sorcery are card types.)
into play.
This deck has a ton going on. There’s even a copy of
Chamber Sentry

{X}, {T}, Remove X +1/+1 counters from this creature: It deals X damage to any target.
{W}{U}{B}{R}{G}: Return this card from your graveyard to your hand.
that can help you convert counters from Gwenna or
Incubation Druid

{3}{G}{G}: Adapt 3. (If this creature has no +1/+1 counters on it, put three +1/+1 counters on it.)
into damage. If anything, this deck shows just how powerful Agatha’s Soul Cauldron truly is.

Storm Herald Combo

If you’re a fan of cool combos but Venturing into the Dungeon isn’t your thing, there’s plenty more cool, casual combos for you to bust out at your local game store. One of the funnier cards to play in a combo is certainly
Colossification

When this Aura enters, tap enchanted creature.
Enchanted creature gets +20/+20.
. What’s better than buffing Creatures immensely? The obvious downside with the card is that it costs a ton of mana, and when you finally suit up your Creature, it becomes tapped.
Fortunately,
Storm Herald

When this creature enters, return any number of Aura cards from your graveyard to the battlefield attached to creatures you control. Exile those Auras at the beginning of your next end step. If those Auras would leave the battlefield, exile them instead of putting them anywhere else.
is the perfect card to help bypass these hurdles. If you manage to get copies of Colossification and
Burning Anger

Enchanted creature has "{T}: This creature deals damage equal to its power to any target."
in your graveyard, casting Storm Herald allows you to win outright! Once you cast Storm Herald, you can attach both Auras onto a Creature you control. Before the tap trigger from Colossification resolves, you can tap your Creature thanks to Burning Anger and dome your opponent for 20+ damage.

Magda Combo

Once you go beyond the card pool available in Pioneer, there are some really funky combos that can be built around. One of the most interesting mechanics to build a combo deck around is certainly Changeling. Thanks to
Magda, Brazen Outlaw

Whenever a Dwarf you control becomes tapped, create a Treasure token.
Sacrifice five Treasures: Search your library for an artifact or Dragon card, put that card onto the battlefield, then shuffle.
, this is quite possible. Magda allows you to make Treasure tokens whenever a Dwarf you control becomes tapped. While there aren’t many powerful Dwarves available in Modern, getting to utilize Changelings opens up the door.
The best Changeling to pair with Magda is definitely
Mothdust Changeling

Tap an untapped creature you control: This creature gains flying until end of turn.
, which lets you tap your Dwarves immediately to generate Treasures. Generally, this deck is designed to generate lots of value and use Magda to tutor cards like
Scourge of Valkas

Whenever this creature or another Dragon you control enters, it deals X damage to any target, where X is the number of Dragons you control.
{R}: This creature gets +1/+0 until end of turn.
to win the game with. Thanks to Magda’s ability to tutor Artifacts, though, you can actually make infinite Treasures by searching for
Clock of Omens

All you need is Magda,
Universal Automaton


You may have this creature enter as a copy of any artifact or creature on the battlefield, except it's an artifact in addition to its other types.
to copy Scourge, dealing a ton of damage to the opponent.

Eggs Combo

Way back in Modern’s early days, there was a rather strange Eggs combo deck in Modern. The goal was to use a bunch of Artifacts that sacrifice themselves to draw cards, such as
Conjurer’s Bauble



{T}, Sacrifice this artifact: Add three mana of any one color.
in the mix, you could net a bunch of mana in the process, and from there, winning was trivial.
Since the banning of Second Sunrise and later
Krark-Clan Ironworks


Search your library for a card, exile it face down, then shuffle. If this spell was bargained, you may cast the exiled card without paying its mana cost if that spell's mana value is 4 or less. Put the exiled card into your hand if it wasn't cast this way.
helped make this deck a bit more consistent. Beseech the Mirror could help tutor up Faith’s Reward, returning all Artifacts from your graveyard that left the battlefield that turn to play.
After drawing a bunch of cards and netting a bunch of mana, you can win via
Bolas’s Citadel

You may play lands and cast spells from the top of your library. If you cast a spell this way, pay life equal to its mana value rather than pay its mana cost.
{T}, Sacrifice ten nonland permanents: Each opponent loses 10 life.
. Citadel lets you sacrifice 10 non-Land permanents to make your opponent lose 10 life. From there, simply cast Faith’s Reward once more, activate Bolas’s Citadel again, and win.

Ruby Storm Combo

Finally, we have a unique Legacy combo deck that is actually rather cheap by Legacy standards. This is because the deck is made entirely of red cards.
Ancient Tomb

The idea is that, with Ruby Medallion in play, you get a discount on all of your red spells. With cards like Jeska’s Will and Seething Song, you can end up with extra mana to use. Between Reckless Impulse, Wrenn’s Resolve, and Galvanic Relay, you can continue to chain spell together, building up your Storm count.
Eventually, you can use Burning Wish to find
Grapeshot

Storm (When you cast this spell, copy it for each spell cast before it this turn. You may choose new targets for the copies.)
and burn the opponent out. Of the deck’s listed here, this is likely the most competitive. That being said, all of these decks could help provide a fun and entertaining night at your local game store, while being fully capable of winning some games along the way. Consider giving one of these wacky decks a whirl at your next event.
