Definitely has some potential.

There is that new 2/1 one-drop for black that was just recently spoiled too!

Yes i know, i'm gonna add it when it becomes available on tapped out.

Foundry Street Denizen over the aspirant.

isn't the War-Name Aspirant better than than the Borderland Marauder , so should i replace that instead.

This deck looks amazing. I feel Foundry Street Denizen is not as strong as a 3/2 for 2. If it was a mono-red deck, then I would understand but with Mardu I feel like you are better off keeping the War-Name Aspirant and Borderland Marauder . +1 from me.

Yeah, I don't think Foundry Street Denizen is needed. You already have a nice mana curve, so you don't need to replace 2-drops for 1-drops. You have to play at least 2 creatures a turn to make Foundry Street Denizen as good, and that's not likely once you've exhausted your opening hand.

Great deck, looking forward to seeing these cards in action! +1

Im pretty sure anything other than 4 Butcher of the Horde is to few

Bertie, I agree. Bloodsoaked Champion and Butcher of the Horde make too good of a combo.

What should i take out to put in the 2 extra Butcher of the Horde .

I would probably take out a Firedrinker Satyr and a Borderland Marauder to make room for the 2 extra Butcher of the Horde . Just my 2 cents.

Errr... I meant Frenzied Goblin , not Firedrinker Satyr .

Magma Jet over Ascendancy. The ascendanct isnt quick enough where as the scry is extremely helpful and it activates the swiftspear.

Nice deck idea! It does look super fast and it also looks like it hits pretty hard as well. I'm not a fan of Firedrinker Satyr though. In my opinion there are better red one drops like Monastery Swiftspear . The prowess isn't a mardu mechanic but it still works with your 10 possible prowess triggers.

Butcher 4x he is the Mardu No.1 Beast, trust me ;)
