Concerning Expir, how did you find out 75% would be the right rate? I personally find at least one combination somewhat OP: if you start immolating or otherwise sacrificing your creatures before dealing the final blow with Fire Bolt or any spell alike with a field of high-cost creatures such as dragons you could gain up to about 50 quanta from your monsters plus 7 more if you used immolation, equaling about 70-90 quanta in one or two turns if set up correctly.
Or in the short version: it would enable making a spam/rush and bolting deck all in one.
Even if you only have a couple of Expirs, the delay is just a few turns and you could always start with weaker creatures. My example might be a bit far-off, but I don't think it's entirely unreasoned.
Just to clarify: does this ability work with the opponent's creatures as well? If so, this+CC+Mindgate might make a decent mirror deck.
Anyways, I'd love to see some of these wolves in the game, many of them are great for countering specific decks. Keep it up.
