I think this deck could lose the Ob Nixilis, Unshackled and a single land of your choice for a trio of a decent target for alesha's activated ability, like Battle Brawler Love the deck!

I agree

I love the use of crackling doom in this deck, I think it wouldn't hurt to make it a playset of them. I don't know who you would take out, the cards all work so well together. Maybe one of the aspirants?

King Macar, the Gold-Cursed could be fun in this. Not sure how "good" he might actually be.

Daghatar the Adamant might be nice to buff your other legendaries/ creatures you want to attack with

I don't like the supplemental combo of Alesha, Who Smiles at Death + Goblin Rabblemaster , it just looks bad for whoever you play against. +1

i really don''t get the use of alesha in this deck. Congrats on the win, but you should definitely be able to find better cards for these slots. Other than a first striker, what are you recurring. Isn't there a 2-drop mono black card that becomes a 3/1 FS when you have a white or red permanent out? Wouldn't that be a better option? I believe that it's an uncommon.

I suppose I could try Anax and Cymede...

What about Sarkhan, the Dragonspeaker? Whenever he +1 he gets the hero's blade.

He doesn't get the blade because he doesn't enter from his +1 ability, he just "changes". However, Sarkhan is still a very good card and is very likely going to win games.

Looking at Dragons of Tarkir, I like Zurgo Bellstriker in either the main board or the sideboard, but not much else has really caught my eye as of yet.

why no use tymaret i mean he is very nasty with rabblemaster
