I think every deck should have a unique attribute and play style, starting with Mega Math.
By default, we have power addition and subtraction mechanics in the game, my suggestion of the day is for Mega Math to have division and multiplication as well. Imagine a card that multiplies the power of the adjacent cards or that divides by half the energy cost of your cards in hand. It would bring a unique mechanic to the Mega Math cards, thematic to the collection and quite strong.
