It's not my top card because it's smaller, costs five mana, and taps so it has to last a turn or you must give it haste to use it and that requires other cards or gives sorcery speed removal or a tapped out for a chance to answer
If that sounds a lot like a sacrifice deck, youd be right
Feast of Dreams only pops an enchantment if its also a creature, in which case any old Doom Blade variant wouldve already done the trick
Theres no body generated, which means that if you dont already have someone to run interference he cant make one
