I read everywhere that Envenom Weapon is bad because you have to kys to remove 2 big threats with it. You don't HAVE to use it on huge threats as an Execute or IDK tho, you can just use it to grab a lot of tempo especially against other tempo/midrange decks. Like for example you dagger T2, Envenom Weapon T3 (you can even Prep it) and then you can remove 2 of their 3/4/5 drops while you develop your board, it really fits with what Rogues want to do

Also somehting on Razorpetal Volley, don't see it as 4 mana deal 2 damage, rather as 2 mana draw 2 bad cheap spells. I'm still not convinced it's good, but bad cheap spells can do work in Rogue
