In the case of Wax / Wane you probably wouldnt play an instant that gives +2/+2 to a creature in a deck, or a narrow effect like enchantment removal
(or lets say you have an army of 6/6 demons, then they all live!) The other card here is Mortarion, who is obviously a fan favorite
It would be nice to see a reprint of this card with new artwork and the opportunity for people to pick up foils for their favorite Commander decks
