I will say that MKM limited is better than I thought it would be. Collect Evidence fucking sucks balls, but everyone knew it would. But Morph 3.0 works out as a mechanic well enough, and there's enough interplay with the hybrid-cost cards that it's pretty involved. You have to both remember the khans rule (anything with morph < 5cmc has 2 toughness or less), but also all of the possible face-down hybrids, which for a given color pair is quite a lot - like, a GR deck can flip up the GR, GW, GB, GU, UR, WR, BR cards.
