Well, you don't need THAT many traps to have bow reliably, he is overdoing it a bit.
Some hunter removal can replace traps. Another Deadly shot, maybe 1 Split Shot. People do not expect split shot nowadays. You can put a Arcane shot in maybe as well, but.. uh. Thing about snipe is that is delays rogue from playing Auctioneer, if you dont have problem with them, you can do without it.
Probably loot hoarder instead of Flare/Thalnos and Kobold instead of Thalnos.
Maybe second drake instead of Greenskin? Or some value creature.
Some other value creature instead of TBK. Like, Savanah Highmane or Argent Commander or Big Game Hunter or .. Well, Kodo if nothing else.
Faceless instead of Rag is ok. So is another Savanah. Ogre is the most budget-y option.
Alextrasza is hard to replace. uh.. anything already mentioned I guess, maybe Argent, it is most burst-y.
