Another good alternative is to draw cards when a certain condition is metlike, say, possessing a creature with four or more power
From attacking artifact dorks like Losheen to attacking tokens with Bennie to attacking with lifelink with Dawn of Hope and The Gaffer, this is a very strong card since it's synergetic with so much stuff
It's also notable that the effect only applies when creatures on the battlefield are exiled - it's no use exiling creature cards from hands or graveyards, which means my first instinct of pairing this guy with various iterations of the MTG planeswalker Ashiok won't work
Final Fantasy's arrival in Commander could've been a hollow fanservice gimmick - all flash, no function
Once the spell resolves, it won't matter if your devotion to green changes
Mad Hatter, Gracious Host Emerald and Ruby offers a fair amount of complexity but not much competitive value
