2: Ouroboroid This cards made to scale and in the right deck, it can get out of hand fast
That means at higher rarities: Cloud, Midgar Mercenary Gilgamesh, Master-at-Arms Firion, Wild Rose Warrior (free 1/1s with job select) Freya Crescent Giott, King of the Dwarves Adelbert Steiner Zidane, Tantalus Thief is also an exceptional card, even without any direct synergy
That said, it'll most often be your own creature targeted with this spell, as you can't control what critters your opponents play, but you can play out your own in such a way to get the biggest benefit
However, green cards can also have it, usually as a secondary perk, and there are a handful of blues that also use it
