1 mana 1\2 "draw" a card is good. It is much better than that stupid rogue's cat because there are no 10 mana pirates or unplayable cards like we have with reborn minions + rogues don't synergize with reborn, warriors synergize with pirates
Putting Anchaar, double Hoard Pillager,double Sky Raider in every Warrior deck regardless of whether or not its a "Pirate" deck.
Do you really need a random pirate in a control warrior (if it will exist)? There are not that many value pirates, what a random 3 mana 3\3 will do for you? Or 8 mana 6\3. I am very unsure about this in slow, dr boom decks
It's a good card to be sure, but I don't think there's much fear of pirate warrior becoming the dominant deck again. The power level of this entire expansion is through the roof and while pirates seem pretty good, I don't think it'll match the overall power the rest of the expansion provides. There's just too many far more broken cards being released for other classes for this to become prominent.
Pirate Warrior may end up as a solid Tier 2 deck but I'm not even sure if that. However, the groundwork has been laid for future pirate power, so it's something to keep a close eye on.
This might again prove the point that the legend cardback should be different depending on what deck you used mostly to get there. My previous, still pending idea for the Evolve Shaman cardback was to feature a golden retriever in front of a computer screen.
