Suggestion for new card: A tech card to deal with chargers

So with the game becoming more and more bursty, I've been thinking about a solution to make the burst combos harder to pull off without destroying them or the decks they rely on. My idea, [this new card](http://i.imgur.com/BuTflj2.png). Keep in mind that stats are not set in stone (pardon my terrible pun), but I do think the it needs at least 2 attack in order to kill the standard charge minions.

The general idea is that this card has to be removed by a minion, a weapon or a battlecry, making it immune to things like sap and soulfire. This means that in order to use your finishing combo you would need some sort of board presence or a reasonably big weapon equipped in order to remove him before blowing someone up with 15 Leeroys. It would be a tech card you'd run in a burst heavy meta, but not otherwise. You would need to play it when you expect the burst to happen, because the minion doesn't offer much board presence on its own and is inefficient stat wise (3 less stats than a yeti). Thoughts?
