I'm actually trying a little different configuration, as Reanimator would be a combo deck.
I think the optimal creature number is 2/3. 2 is better, but often we would a different solution from shround.
So, this is my list
// Lands
4 [ON] Polluted Delta
4 [R] Underground Sea
2 [DD2] Island (1)
4 [ALA] Swamp (1)
3 [ON] Bloodstained Mire
1 [ON] Flooded Strand
// Creatures
1 Iona, Shield of Emeria**
1 [DIS] Tidespout Tyrant

(try it before comment

)
1 [CFX] Inkwell Leviathan
// Spells
4 [CST] Brainstorm
4 [TE] Reanimate
4 [US] Exhume
4 [LRW] Thoughtseize
4 [MI] Mystical Tutor
4 [NE] Daze
4 [AL] Force of Will
4 [OD] Entomb
3 [LRW] Ponder
3 Spell Pierce**
// Sideboard
SB: 3 [DS] Echoing Truth
SB: 3 [FD] Engineered Explosives
SB: 3 [10E] Pithing Needle
SB: 1 [ALA] Empyrial Archangel
SB: 1 [ALA] Hellkite Overlord
4 open slot
