Idea is for it to stack (points to post), but since that it only lasts for 3 turns you would have to have most of the quanta AND cards PLUS something that can kill the enemy creatures off. It has potent synergy, as you said, with malignant cells.
But also:
Skeletons/graveyard
Fireflies (or other mass-produced, low-hp creatures)
Photons
Sparks! (self-inflicted, woho!)
Rustlers
And: Thunderstorm, rain of fire, flood, plague (retrovirus) plus several mounts suggested in the card ideas section.
And of course: Fireshield and spiked carapace. (if spells are included, it also works well with bone wall, for obvious reasons).
A mass of scarabs, otys, flying owl eyes, etc, could also prove fairly effective.
Thank you Boingo! master post updated (I'll upload the higher resolution pics if these make it to the higher levels)
