Such an amazing weapon! Finally a cheap weapon to use buffs on. Amazing target for Envenom Weapon, Leeching Poison, Blade Flurry, all sorts of things!
I was super jealous when warrior got N'Zoth's First Mate and thought that it would be amazing to have a low cost, decent durability weapon to combo with Buccaneer, Deadly Poison, and Leeching. Knowing that the buffs are retained when you get it again is just icing on the cake.
It's good but not game-winning because it's a 1-mana weapon and Blizzard obviously tested this already. With Deadly Poison, it's a 3/3 weapon for 1-mana which is only ok in the late-game. With Envenom Weapon, it can destroy 3 minions but Rogue's health is a problem. 1-attack means Leeching Poison is useless, unless you're willing to play a weapon Rogue that revolves around a 1-mana legendary weapon.
Oh Lord, this looks incredible. Just getting a Deadly Poison on it gives you a 1-mana 3-3 weapon for the rest of the game. This even makes cards like Leeching Poison viable since having a low-cost, high-attack Lifesteal weapon always in your deck is pretty crazy for Rogue. It's by no means a consistent source of life gain but it's impactful when drawn.
Here's hoping they release 1 or 2 more weapon enchantments for Rogue. This card may just be crazy.
This weapon is so good. I actually don't think its effect is that relevant unless you're playing Miracle or Mill though. In tempo rogue it's not too likely you'd use all the charges and then draw this again before the game is over.
But this will see a lot of play. Buffable 1 mana 1/3 weapons have a history of being dominant (hello Spirit Claws).
