What's a decent substitute for Dr. Boom?

I think Grommash is better for this deck.It's a great finsher.

If you only want to play this deck or Warrior, Grommash Hellscream is better. Dr. Boom is better in every other class though.

Dr. Boom is a neutral orange,so you can have him in multiple decks

Unstable Ghoul or Dread Corsair

for this deck grommash, but you should craft dr. boom

Willing to believe this is one of the best decks in the meta. Nice work!

I swapped out Bloodmage for Nat Pagle and it's actually worked wonders. If you're able to mulligan for Pagle and play him with a coin or on turn 2, he pays off well with card draw and can even be a surprise buff with Inner Rage, Cruel, or battle rage.

What can you use instead of bloodmage thalnos 

Kobold Geomancer if you want the spell damage bump for the same cost as Thalnos.

he's not played for his buff, he's played for his card draw. The buff is just extra

But why would he need a buff for slam and wirlwind only ? Isn´t loot hoarder much better for this deck ? I tried playing this decklist with bloodmage, and it is kinda useless as +1.

Armorsmith is pretty much a staple in all the Warrior decks, well worth the 100 dust.

Substitute for  Grommash Hellscream?

Unstable Ghoul or Dread Corsair

ty i was wondering what to replace had no idea.

Chromaggus?

Why bloodmage? I didn't watch his entire stream so might have missed the explanation. 

Try him out, I used him instead of hoarder last season, he's quite good ! Sometimes +1 Spell Dmg can be huge for board clearing, if you feel like giving up 1 damage from the hoarder.
