Video GamesThe Ten Journey to Un'Goro Cards That Will Define The MetaVideo Games - RSS 2.0
At some point in the development of this expansion, Blizzard realized they had made a huge mistake with Pirates in Mean Streets of Gadgetzan. Even after nerfs to Small-Time Buccaneer, Pirate Warrior remains one of the most consistently good decks in the game. So, in order to rectify that mistake, we've been given not one, but two tech choices against the dreaded deck.
Golakka Crawler is the much more situational card of the two, and will probably only see play as an anti-Pirate card if Pirates remain very heavy in the meta. Ironically, it can also be a good card for a Pirate deck - you can eat your own Patches on turn 2 to make a two mana 3/4.
Gluttonous Ooze, on the other hand, is a much better counter. Against Pirate Warrior, it's pretty much GG if you eat their upgraded Arcanite Reaper and gain 6-7 armor. It's also a better tech choice than Golakka Crawler because it's effective against four out of the nine classes (five if you count Jaraxxus). I expect to see it replace Acidic Swamp Ooze in most decks.
Or, if you really, really hate Pirates you can run two copies of each.
