Out:
Phyrexian Metamorph - Only a value creature, since its combo with Sharuum is useless, since we don't have the kill piece (Disciple of the Vault, Altar of the Brood). It was useless in most situations, so it got cut.
Sharuum the Hegemon - Fun for some reanimation shenanigans, but doesn't do much for its cost, plus it doesn't have any more use as a combo piece.
Relic of Progenitus  - Two pieces of grave hate were enough for the majority of the time. It also can't be recurred and hits our own yard.
Talisman of Indulgence - Temporarily out, replaced by springleaf drum.
In:
Sram's Expertise - Gives us three chump blockers / artifacts to feed to Breya, turns on metalcraft, plus gets us a free 3CMC spell.
Memory Lapse - I feel like i usually have trouble getting protection when i combo off. Sub-optimal, but included because it's the only counterspell i have at hand at the moment.
Galvanic Blast - Included because it hits most of the creatures we want dead, exceept for the really large ones. It's also a non-white 1cmc creature removal, so we aren't too dependent on one color.
Springleaf Drum - A dumb idea I'm trying out.
