I think we could have an Elder that is somewhat focused on Mutation.
What about the entropy-life AI3?
It seems a bit more unwieldly and life-ish. I wanted an AI that was all about getting freaks and abominations an such - with novas to power their abilities.
Well, it's not using novas, but here's the unupped version of my favorite deck:
4sa 4sa 4sa 4vc 4vc 4vc 4vc 4vc 4vc 4vc 4vm 4vm 4vm 4vm 4vm 4vm 4vn 4vn 4vn 500 50u 5bs 5bs 5c4 5l9 5l9 5l9 5l9 5l9 5l9
The AI needs an upgrade so that it can use fallen elves properly. If it happened, that elder would be a lot more fun and fearsome.
By the way, Elder decks shouldn't have 30 cards. They all have about 40 cards, and I think it is fine this way: we don't want their decks to be too focused. We could simply give them grabbows and firestalls, but that wouldn't be any good.
Anyway, here's an Elder idea I had. Originally it had devourers but as testing showed me, the AI uses mitosis only on creatures with at least 1 attack, so I put in some other stuff instead.
4vc 4vc 4vc 4vc 4vc 4vc 4vc 4vc 4vh 4vh 4vh 4vh 4vh 4vi 4vi 5c3 5c8 5c8 5c9 5c9 5c9 5c9 5de 5de 5de 5de 5de 5de 5de 5de 5de 5de 5de 5de 5ur 5ur 5ut 5ut 5v1 5v2 5v2 5v2
