@first comment, nope, not really the case of being beaten too many times with it. Sanctified Darklord quickly snuffs out Despacito’s effect. I just think it’s a really cheap way to win is all.
I don’t have a problem with the skill itself, like when people were abusing MT with Subterrors people are using MoD in a way that wasn’t intended. Like you say, it should require a certain amount of Arcana Force cards in your deck for it to activate.
