Sabredancer and Cocytus are already here and I'm sure thay they will release more. 90% of the cards have the word "target". A single word can ruin a lot of cards in the game. This card is so much bettet without that word.
Dustflame Blast is even better than this card as it can destroy more, on your side too and also doesn't target, but sadly it's part of a not so popular archetype
