I've noticed a bit of synergy between a few cards that seem to make the game more fun.
I haven't played long, but have 6 upped cards 5 of which are Fallen Druids.
If you use the Death card Aflatoxin on your own creature and follow it up with Empathetic Bonds, Heal, and Fallen Druid mutation the damage, healing, and skills stack up very quickly.
Most of the time I'll get a mutant with Devour to use on a Malignant Cell and play a creature I'd like.
Seems that mutating a Malignant Cell leaves the poison symbol, but no poison damage is received.
Let me know if there are other cards I could be using to improve this, please.
Thanks!
