zombie mtg cards Subtype: Zombie, Colors: Blue, 104 Activate this ability only any time you could cast a sorcery. Zombie Master — Wizards Play

1 Sky Diamond

This dodges most things you want to get through, but it isnt like commander damage is your win condition anyway if your opponent has some random black creature

Invasion of Kamigawa // Rooftop Saboteurs doesnt seem to evoke the blue imagination that much as well, although it is kind of fairly usable on its own if the user decides on the whittle down option

Summon the Painbow There is a lot of cross over for some five color legends among these categories, but I think most fit one over another

This card will win games
