Avigraft seems too slow for some games, I might consider including Defiance instead, or Fall Short in a meta where cards with unique text but no battle skills are becoming a problem. Ijin + Golem Press can rescue a lot of games where your opponent has early removal or board sweeps, or generically anything that tries to hit units in hand or remove them from deck. I've tried this with Ijin's Workshop but so far it seems too slow, think that may require a few more units that are low to the ground.
