Everyone loves a good Mesmeric Fiend, right?
Definitely a powerful card back when it was printed, it's an effect we haven't seen in quite some time. Until now, that is.
So that art is sweet, right?
Besides that, I expect that this will see some play. Not a ton, since Sin Collector kind of fills the role even better right, but more effects that take the best card out of your (usually Control) opponent's hand are always good. If you take their Supreme Verdict with this, they're going to have to do something they usually won't want to in order to get it back. This allows your guys to continue to beat in while they have to deal with a 1/1 just to get their Wrath back.
Like I said, it's a role that Sin Collector excels in right now, but I think Maggot will have a place before it rotates.
