Scourge of Valkas and Dragon Tempest are two of the best finishers for dragons, letting you deal damage and win outside of combat
(Players dealt combat damage by that creature also get a poison counter.) Giving an attacking creature flying after it has become blocked will not cause it to become unblocked, even if the blocking creature can't normally block creatures with flying
They could have given it no casting cost at all, and it would be almost as prolific and still just as painful
