Mana can go below zero
I'm sure many of you are already familiar with this info given how the most people in this lounge are eyeing on Twitter constantly, but I've brought this here to ask for opinions. Since modification is a permanent effect, if it is possible, do you think it's wise to build a deck based on mana modification? By modifying your opponent's total number of mana below zero, I think there's a possibility to win early in the game by seizing the ability to play cards at all. What do you think?
