With a cost of 4|3, this'll never be OP or even remotely close to it. Denial decks don't leave you with 4 quanta in any element until the denial doesn't matter anymore and you're dead or soon to be dead. Anyone who has played with and against a Discord rush deck knows this. It's more useful for rainbows as defense against Black Hole right now.
Never say never, oops I just..... never mind.
Anyways I agree for awhile atleast this can never be OP. SoG is much better and cost less and is other. There is only 3 other reasons I can think of to use this card. I still love this card though.
Also I agree about the cost, it wont be OP until something big changes.
On a side note I believe between this update and the last one fire and life have remained untouched. I think that if we get more cards this update they will prolly be fire or life. Right?
