The new “Team-up” Legendary creatures are possibly the most exciting aspect of the upcoming MTG Set, March of the Machine. Iconic characters from Magic’s past are banding together on a single card to fight off the Phyrexians. Cards such as
Thalia and the Gitrog Monster

You may play an additional land on each of your turns.
Creatures and nonbasic lands your opponents control enter tapped.
Whenever Thalia and The Gitrog Monster attacks, sacrifice a creature or land, then draw a card.
,
Yargle and Multani


Whenever you attack, choose one —
• Create a tapped and attacking X/X green Dinosaur creature token with trample, where X is the greatest power among other attacking creatures.
• Create X 1/1 white Vampire creature tokens with lifelink, where X is the number of other attacking creatures.
have, broadly, been received warmly by MTG fans. Members of the community on Reddit are even discussing their own ideal MTG team-ups.
Not all of the team-up cards in March of the Machine will be Standard legal. At last week’s March of the Machine First Look event at MagicCon Philadelphia, three team-up legendary cards were announced. These cards are not a part of the main set itself. Although these cards will be included exclusively in Prerelease kits, they will not actually be usable at the Prerelease event. The cards are designed to be powerful Commanders, let’s give them a look…
Katilda and Lier

The first of our cards depicts a pair of Innistradi spellcasters,
Katilda, Dawnhart Prime

Human creatures you control have "{T}: Add one mana of any of this creature's colors."
{4}{G}{W}, {T}: Put a +1/+1 counter on each creature you control.
and
Lier, Disciple of the Drowned

Each instant and sorcery card in your graveyard has flashback. The flashback cost is equal to that card's mana cost.
. This card combines Katilda’s Human tribal elements and Lier’s focus on flashing back Instants and Sorceries from the graveyard.
When this card was first revealed Dave Humphreys, the lead designer of March of the Machine, put forward a brief argument to explain its appeal. He said: “The elevator pitch here is pretty much all of your humans become Snapcaster Mages“. While this description isn’t quite accurate, Katilda and Lier don’t grant all of the humans in your deck Flash, there is still a very, very powerful Human tribal/Spellslinger deck that can be built around this Commander.
Fortunately, given that Humans are the most populous tribe in the game, there are already a huge number of Human cards that support Spellslinger strategies. Cards like
Baral, Chief of Compliance

Whenever a spell or ability you control counters a spell, you may draw a card. If you do, discard a card.
and
Wizards of Thay

Instant and sorcery spells you cast cost {1} less to cast.
You may cast sorcery spells as though they had flash.
will make your spells cheaper both to cast initially and to Flashback later on.
Monastery Mentor

Whenever you cast a noncreature spell, create a 1/1 white Monk creature token with prowess.
and Murmering Mystic will develop your board presence while your spells go off. Additionally, low-cost Humans like
Recruitment Officer


As for the Spellsligner side of the equation, there are some Instants and Sorceries which really stand out in this deck.
Mass Appeal




Choose any number of target opponents. Create X 1/1 white Human Soldier creature tokens, where X is the number of creatures those opponents control.
is a very useful Instant for creating a lot of Human Creature tokens quickly.
Goro-Goro and Satoru

This Akki Samurai and Human Ninja from Kamigawa form a rhyming pair.
Goro-Goro and Satoru

{1}{R}: Creatures you control gain haste until end of turn.
generate a 5/5 Flying Dragon token whenever one or more creatures you control deal combat damage to a player on the turn they have come into play.
Goro-Goro and Satoru’s ability to grant creatures you control Haste makes it easier than it might seem for this effect to work, so you won’t have to fill your entire deck with Hasty attackers. Appropriately enough, this commander also works well with creatures that have Ninjutsu. Ninjas generate Dragon tokens, as they swap straight into play from the hand, attacking as they enter the battlefield.
One ability that synergizes particularly well with this Commander is Myriad. Since the copies generated by Myriad come straight into play attacking, they are eligible to generate dragon tokens so long as they don’t get blocked.
Blade of Selves

Equip {4}
and
Elturel Survivors

As long as this creature is attacking, it gets +X/+0, where X is the number of lands defending player controls.
fit nicely into any Goro-Goro and Satoru decks.
Some other cards to consider are
Kiki-Jiki, Mirror Breaker

{T}: Create a token that's a copy of target nonlegendary creature you control, except it has haste. Sacrifice it at the beginning of the next end step.
which can create Hasty attacking clones of your best threats, ready to spit out more Dragons.
Dragon Tempest

Whenever a Dragon you control enters, it deals X damage to any target, where X is the number of Dragons you control.
a card that can deal out a pretty significant amount of damage as you start to build up more and more Dragons, with the additional upside of granting any flyers in your deck Haste. Finally,
Purphoros’s Intervention

• Create an X/1 red Elemental creature token with trample and haste. Sacrifice it at the beginning of the next end step.
• Purphoros's Intervention deals twice X damage to target creature or planeswalker.
can grant you a Hasty attacker with Trample that is almost guaranteed to get some combat damage through, as well as acting as a removal spell in a pinch.
Slimefoot and Squee

The last of the three Prerelease exclusive Commanders are
Slimefoot and Squee

{1}{B}{R}{G}, Sacrifice a Saproling: Return this card and up to one other target creature card from your graveyard to the battlefield. Activate only as a sorcery.
, a Dominarian duo of Weatherlight warriors. This Commander has gotten the community quite excited, with some players even arguing that the card has Competitive EDH potential. Slimefoot and Squee create a 1/1 Saproling token whenever they enter the battlefield or attack. They can also be returned from the graveyard to play, along with another creature, by paying 4 mana and sacrificing a Saproling.
Players have already brewed some powerful combos that can close out the game quickly using this card’s effect. As long as there are five or more Artifacts or Enchantments in play under the control of your opponents, this card can secure a win alongside Dockside Extortinonist and
Goblin Bombardment

This card can also enable some powerful reanimator strategies. Putting an effect that resurrects dead creatures in the Command Zone is very powerful. These reanimator strategies use targeted effects that send cards from the library into the graveyard like
Entomb



When this creature enters, creatures you control gain trample and get +X/+X until end of turn, where X is the number of creatures you control.
,
Griselbrand

Pay 7 life: Draw seven cards.
or
Archon of Cruelty

Whenever this creature enters or attacks, target opponent sacrifices a creature or planeswalker of their choice, discards a card, and loses 3 life. You draw a card and gain 3 life.
. This gives you access to your most powerful cards many turns before you would normally have the mana to cast them.
Will Slimefoot and Squee live up to the hype or will this Fungus/Goblin pair end up wilting under the harsh light of day? Once March of the Machine comes out, we’ll be able to find out.
