I tried putting togeather a couple decks based around this card in the trainer, my first idea was Chimera + armerigos + fractaled ball lightnings. My second idea was Chimera + Shriekers + Basalisk's blood + Earth Nymphs. After tweaking these decks I finnally got the ball lightning deck up to maybe 30-40% win rate against lvl 5 AI and the Basalisk's blood to 50%, but that's nowhere near the win rate of alot of other upped (and a few unupped) decks I've taken against AI5.
Basalisk's Blood deck
6rn 6rn 6rn 6rn 74g 74g 778 778 778 778 778 778 778 778 778 778 77f 77f 77h 77h 77h 77h 77h 77h 77l 77l 77l 77l 77l 77l 77s 77s 77s 78q 78q 78q 78q
Although able to make 20/100+ chimeras after about 7 turns pretty much every time, most decks can kill this off pretty quickly since it doesn't have a permafrost or diamond shield attached to it
I'm not sure how Chimera could become a more mono/duo friendly card, but for now it looks like a final smash for rainbow decks meant to last only 1 or 2 turns and bypass shields.
