Bacteria is a ripoff of Malig. Cell, and is cheaper, so I think it's somewhat OP.
I don't understand what Ying Yang does.
Desert seems balanced, but somewhat redundant because of stone skin.
Flame seems okay, but Fireball just seems a little overpower since it's 4 fire for a 7|2, which puts it out of range of minor CC. Maybe make it 7|1 instead?
I think pyramid would be better if it had a cost of 4 Time to reincarnate a mummy and it was a permanent.
I don't really like the idea of Soul at all...
Dead/kill tree are WAY redundant, as Life has enough vanilla creatures as it is.
Ocean is just a water eclipse, but cheaper.. kinda unoriginal..
Jupiter comes into play with gravity pull? I like it kind of, a better version of armagio.
I love the lethal injection, like arsenic kind of. It would go better with death, though.
Change is a nice concept for rainbows, but it should go in Entropy in my opinion.
I like the butterfly; air is in need of some middle ground vanilla.
Change points is widely unbalanced. Armagio, a 25/2 for 12
. Titan, a 70/8 with momentum for 16
or 15
1
. Just... no.
