Do you mean the quanta generation of the pillars are completely nullified PLUS the quanta drain, or just simply quanta drain that can be counteracted by the quanta generation of the pillars?
pillars are completely nullified PLUS the quanta drain this will be very usefull against mono decks
The wording should be changed to: "Select a group of pillars, they will now consume 2 quanta of their element instead of generating quanta for 3 turns"
Also, for quantum pillars, they should consume 3 random quanta...
