How about not? Here's the tradeoff:Two guaranteed quanta every turn.No more than six in a deck.Sound good?
An idea for introducing these cards: combine two towers (upgraded pillars) to get a dual pillar. Then you can upgrade the dual pillar to a dual tower in the normal way.
No. You set it, you get 2. Every turn, you get 2.Considering you get 3 from quanta tower, there's nothing wrong here.
