Abrupt Decay: I really don't have many problems with mentor/pyromancer personally; and if it's already generated a bunch of tokens, AD/Swords/Path/whatever won't save you at that point. Phyrexian Revoker (which I noticed you weren't playing) shuts down some of the cards you brought up and so does Stony Silence. Having a nice, clean answer to Oath is great, but I'd just play BUG Leovold at that point since I feel like it's going to be a better deck (maybe?).
Mana Crypt: After making my opponents lose to their own Crypt and seeing it kill numerous people, I'm not convinced especially in a deck that is not a combo deck. There are plenty of games that go long, and this deck isn't exactly packing life gain, but that's less of an issue if you have DRS. There are going to be games where Crypt is way better than Sol Ring, but I don't like including cards in my deck that can cost me the game when there are acceptable (and better in some cases) alternatives.
Edit: After a few play test games thinking about it, Sol Ring doesn't really make a lot of sense since it goes against the philosophy of "play dudes on turn 1."
What do folks think of the follow idea as a way to expand upon Human Stompy? There are definitely gaps in this list in terms of matchup coverage, but it could be a very interesting new twist to the deck:
Rainbow Human Evolution:
4 Cavern of Souls
4 City of Brass
4 Gemstone Mine
4 Mana Confluence
1 Strip Mine
1 Black Lotus
1 Mox Emerald
1 Mox Jet
1 Mox Pearl
1 Mox Ruby
1 Mox Sapphire
Creatures - By Function - (30):
Mana Dork/Mantis Buffer:
4 Noble Hierarch
Protection i.e don't remove my toolbox cards!:
4 Mother of Runes
Eldritch Evolution needs to resolve and general awesome creature:
4 Grand Abolisher
4 Thalia, Guardian of Thraben
1 Grand Arbiter Augustin IV
Seems reasonable, but i am really not liking kataki. I was testing against Doomsday and I was surprised by how much game the deck had. I think cutting kataki for hammer mage and then playing chalice seems real interesting.
