Skill Drain isn't broken

I keep seeing people complain about skill drain being an "end all be all" of a game and act like it's so broken that the game is auto decided when it's played. There are so many decks that require back row removal that people already have cards like harpies, or twin, or MST (to name a few).

To me,a card is broken if it can ONLY be negated/destroyed/blocked by very specific cards that aren't put into most decks due to their limited usefulness.
