Break Expectations
Donate cards to your opponents' card pools which do weird, wonky, and warping things to various aspects of the game.

Cursebound Witch
Easily the most cursed of the spellbooks. It literally wants to fill your cardpool with curses and curse enhancers and enablers.

March Toward Perfection
Phyrexian creatures.

Imperial Blademaster
Work in progress. Likely going to reduce to single attacker bolstering Samurai/Warrior tribal and maybe move Exalted cards to general draftable pool.

Not Included:
Garruk, Wrath of the Wilds
Not a fan of the first ability.
