Flavor: Tricking everyone gives You an edge. A sharp, pointy edge.
Opinions? I would like to get better at this.
As another said, it needs to say "double this weapon's attack"; because right it reads that it only doubles when attacking the hero.
@DestroyeR thanks for your opinion. I was debating 2 or 3 durability. I'm still not sure what is the correct number. I don't think there are to many buffs for weapons over all that made me go to 3 durability. And yeah I know kingsbane can go to 20+ attack but that weapon can't be destroyed. Additionally You can easily buff it over the time of playing it 3-5 times.
Trickster weapon has only 3 charges. That's it. You have to use all buffs between playing and attacking for 3rd time. Weapon destruction will make this weapon useless. Especially Gluttonous Ooze. You can get back all that health in armor.
Another part of this is the weapon only doubles when attacking a hero, and as a clearing tool it's garbage (especially by turn 5), so this is exclusively a face-hitting tool or a really inefficient emergency removal one. I kinda doubt this would get played without the exact right cards to fit with it, so you don't need to nerf it, but I'm not sure you can lower its mana cost either. You could consider making it cost 4 but I'm pretty sure the durability is fine.
Important thing to keep in mind is just how much support this card needs to be strong. And you already only get two attacks with enhanced stats; the first will be un-doubled. It would be useless at 2 durability unless it tripled its attack or something.
