• All the mutate cards I can play in these colors
• Creatures that bring other creature cards back to my hand (so I can recur mutate cards)
• Mana ramp creatures that have 0 power in graveyard (can get a bunch of these back when Nethroi triggers)
• Creatures that have 0 power in graveyard but large power on battlefield (e.g. it enters with a bunch of +1/+1 counters)
I was going to have some sac outlets in there (to form a "loop"), but I simply ran out of room. I might cut some mana ramp to do this. (The deck currently has perhaps too much mana ramp in it.)
