"Wonderful weapon! Just... look out to not cut yourself by accident with this."

My look and Reborn weapon. This one goes to Rogue and have typical stats - 3/2 for 3 mana. But effect is quite powerful but balanced in my opinion.
Gaining two cards, mostly of your choice can be really helpful. Especially in late game when you hit some big guy. Don't mentioning extra synergy with thief archetype, if you get a class minion. Of course we need to kill it first, what mean getting extra damage, but its always a case with using weapons. Reborn allows to immediately gain first killed minion, but buffs (like from Deadly Poison for example) will not retain.
It could generate even more cards, in Wild thanks too Doomerang or Runeforge Haunter, or when in standard we will get a Upgrade! from other Rogue's cards.
