This deck easily counters all forms of shaman and renolocks, now this doesn't mean they're a free win because managing your board clears and removals are very important. Using brann properly is key!
Jade druid is the weakness of this deck as it can't keep up once chain summons of 6/6s come.
in pirate warrior games your opening hand often determines the game, still with a little luck and correct play this deck maintains a 60% winrate vs them. You'll want taunts and kazakus for sure and Reno wouldn't hurt either.
