A Sin Magic: The Gathering card in Universes Beyond: Final Fantasy would be spoiled for mechanical choice
The lack of red mana in this theoretical deck puts a limit on the number of Final Fantasy Wizards you can consider, but theres still Venat, Heart of Hydaelyn, who lets you draw a card every time you cast a Legendary card
In some cases, the MAR card just has new art, like Path to Exile, Relentless Assault, or Heroic Intervention
Any curve with Nissa, Voice of Zendikar should be incredible, as should landing Armorcraft Judge after a Verdurous Gearhulk, although its likely overkill at that point
So, Wizards made the partner mechanic, which lets you have two legends in the command zone, as long as they both have partner
They can be printed at home, or hastily drawn on paper
