The Explorer format is fresh and new at this point in time, but it’s going to become Pioneer eventually. We saw
Winota, Joiner of Forces

Today, we’re going to talk Explorer, and 23 cards that the Explorer format needs to feel more like Pioneer. Yes, all of these cards will make it eventually, but adding these cards now flushes out a lot of the format, and even could make Winota ok to unban.
The List
If you want to listen to more of my thoughts about each card, check out the video above! There’s 3 cards for each color, with a few more for Multicolored and 3 for lands.
Red



To kick off the red cards,
Monastery Swiftspear

Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
and
Eidolon of the Great Revel

Collective Defiance

Choose one or more —
• Target player discards all the cards in their hand, then draws that many cards.
• Collective Defiance deals 4 damage to target creature.
• Collective Defiance deals 3 damage to target opponent or planeswalker.
is an inclusion in Izzet Phoenix and Control decks. The Izzet decks have been struggling to get off the ground, and have had to retool their cards to make the deck work. It’s become a different deck from what is in Pioneer. This, alongside another card in our list, will help those decks out.
Green



In the Green camp,
Elvish Mystic


{T}: Add one mana of any color.
are essential redundant mana creatures that the green decks have been craving.
Gilded Goose

When this creature enters, create a Food token. (It's an artifact with "{2}, {T}, Sacrifice this token: You gain 3 life.")
{1}{G}, {T}: Create a Food token.
{T}, Sacrifice a Food: Add one mana of any color.
is ok, but nowhere near as good. Not to mention Sylvan Caryatid is utilized in a few different decks so this is a nice addition to work towards those.
Oath of Nissa

You may spend mana as though it were mana of any color to cast planeswalker spells.
isn’t a huge format staple, but it’s one that’s helping to enable the Mono Green
Storm the Festival

Flashback {7}{G}{G}{G} (You may cast this card from your graveyard for its flashback cost. Then exile it.)
Deck. That deck sees a fair bit of play in Pioneer, and it’s close to complete in Explorer, so adding this piece would be nice.
Blue



Speaking of the Izzet decks,
Thing in the Ice

This creature enters with four ice counters on it.
Whenever you cast an instant or sorcery spell, remove an ice counter from this creature. Then if it has no ice counters on it, transform it.
is the other card that will help. It’s one of the main win conditions of the deck. It plays similarly to something like
Smoldering Egg

Whenever you cast an instant or sorcery spell, put a number of ember counters on this creature equal to the amount of mana spent to cast that spell. Then if this creature has seven or more ember counters on it, remove them and transform this creature.
, but it’s far more powerful.
Mausoleum Wanderer

Whenever another Spirit you control enters, this creature gets +1/+1 until end of turn.
Sacrifice this creature: Counter target instant or sorcery spell unless its controller pays {X}, where X is this creature's power.
is next, and is the sole missing piece from the Mono Blue Tempo / Spirits decks, and is also included in the Bant variants as well. It’s another early game creature to help get the deck going. It also provides a free, and powerful counter spell in a pinch.
Jace, Vryn’s Prodigy

Black



As for Black, honestly, the color has a lot of their tools already in the format. There’s just a few things missing.
Kalitas, Traitor of Ghet

If a nontoken creature an opponent controls would die, instead exile that card and create a 2/2 black Zombie creature token.
{2}{B}, Sacrifice another Vampire or Zombie: Put two +1/+1 counters on Kalitas.
is a premier tool in Pioneer to help deal with creature based strategies, and it’s sorely missing in Explorer.
Bloodsoaked Champion

Raid — {1}{B}: Return this card from your graveyard to the battlefield. Activate only if you attacked this turn.
is another strong 1 cost creature to help get the Mono Black Aggro decks up off the ground. While we have
Dread Wanderer

{2}{B}: Return this card from your graveyard to the battlefield. Activate only as a sorcery and only if you have one or fewer cards in hand.
, it’s about the critical mass of these cards that helps the deck function properly.
Lastly
Collective Brutality

Choose one or more —
• Target opponent reveals their hand. You choose an instant or sorcery card from it. That player discards that card.
• Target creature gets -2/-2 until end of turn.
• Target opponent loses 2 life and you gain 2 life.
is a card that is a staple in Modern, but has fallen off a bit in Pioneer. It’s been recently picked back up in the various Greasefang decks of the format. All in all, it’s still a versatile and strong card that people like, and so it’d be a great addition to Explorer at this stage.

White



White has only a few really necessary cards that it needs to bring, as it’s more of a splash color in Pioneer.
Chained to the Rocks

When this Aura enters, exile target creature an opponent controls until this Aura leaves the battlefield. (That creature returns under its owner's control.)
is a very strong removal enchantment, and is the only missing piece from most of the
Fires of Invention

You may cast spells with mana value less than or equal to the number of lands you control without paying their mana costs.
decks. Though it doesn’t move the needle on the decks power, so there’s no reason to not bring it in.
Favored Hoplite

Thalia’s Lancers

When this creature enters, you may search your library for a legendary card, reveal it, put it into your hand, then shuffle.
is a pretty out there pick. Only seeing play in the Mono White Devotion decks, it’s a vital piece for the deck. It helps to search up the decks heavy hitters like
Golos, Tireless Pilgrim

{2}{W}{U}{B}{R}{G}: Exile the top three cards of your library. You may play them this turn without paying their mana costs.
and Emrakul, the Promsed End.

Multicolored






We have 6 total cards for our Multicolored section.
Voice of Resurgence


Destroy all creatures.
is one of the best sweeper in the game, and it’s one of the few missing pieces from Azorius Control.
Reflector Mage

Boros Charm

• Boros Charm deals 4 damage to target player or planeswalker.
• Permanents you control gain indestructible until end of turn.
• Target creature gains double strike until end of turn.
and
Izzet Charm

• Counter target noncreature spell unless its controller pays {2}.
• Izzet Charm deals 2 damage to target creature.
• Draw two cards, then discard two cards.
are very powerful tools for their respective decks, and given that they’re uncommon, they are very easy to include in the grand scheme of Historic Anthology 6.
Lastly,
Spell Queller

Flying
When this creature enters, exile target spell with mana value 4 or less.
When this creature leaves the battlefield, the exiled card's owner may cast that card without paying its mana cost.
is a key piece of the Bant Spirits deck, which hasn’t seen much play in Pioneer lately. Though it’s still a great pick for a deck to take a random tournament down, or possibly to ladder with!

Land



We have 3 lands to talk about, starting with
Urborg, Tomb of Yawgmoth


The one high risk pick here though is
Nykthos, Shrine to Nyx

{2}, {T}: Choose a color. Add an amount of mana of that color equal to your devotion to that color. (Your devotion to a color is the number of mana symbols of that color in the mana costs of permanents you control.)
. Generally speaking, the only devotion deck that’s got some fight to it is Mono Green Storm. Though Mono Black devotion and Mono White both have some showings in Pioneer, and this is a big part of making all of these decks work.

I think that if these cards were to be included, it’s possible that Winota could even be unbanned. We could have a nearly 100% meta functional Pioneer right off the bat. There are a few cards and decks still missing, though those cards total to probably another Anthology’s worth.
