Rakdoss Return Ive touched on this a few times, but the combination of a discard effect and pressure on your opponents life total is highly effective
One of my favorite formats of all time combines Five Color, Highlander, and Pauper, into a deck that requires 250 cards, 20 cards of each color, only commons, and no more than one copy per common (other than basic lands)
Thank you for sticking with me to the end
Another advantage that this card provides is the simple fact it banishes all dead minions from both players cemetery
The old combo, which never saw any real competitive play, required a hefty four cards to do anything meaningful, as well as an exerted character on your opponents side of the board
