Hmm, looks like it boosts duo decks while not helping rainbows in the slightest. An excellent choice!
yep, i like it!
but i think it should treat pillars and towers of the same type together...we don't wanna nerf towers do we? it'd just make things weird.
also the upgraded version of this compared to the unupped version is much stronger than towers vs. pillars. maybe just have it produce a quanta of your mark when played? or even better (but could be too complicated to fit on the card) it just gives double production when its played...like if you have a
stack and a
stack out when its played you get
when played then again at the end of the turn, just like with normal towers
