Homeward Path in place of Hammerheim, unless your meta is filled with walk abilities this is what I'd do. Avalanche Riders, Fulminator Mage, and Returned Centaur are the cards I think are most underwhelming. I also don't think land destruction is fun so I'm biased against two of them but without a combo going they don't do anything impactful most the time. Glory can be really nice if you want a bit more protection.

Thanks for the feedback. This deck is my most "competitive" 1v1 deck and the only one that has land destruction. I want it to be as cutthroat as possible, but still not all powered. That is why I chose a tier two commander and didn't include the cards that cost over a hundred dollars. Also there won't be any durdling after destroying their land so I don't think it will be boring to them as it will be over quickly I hope. I like that the returned centaur can be reused to continue to put other creatures into the graveyard from my library when needed. Admittedly it is a weaker card in the deck but it is there to help with feeding the graveyard(I think that is the weakness of this deck but I could be wrong). I like glory and will try to find room for it after some play testing to see if it is needed. The deck description has been fleshed out and some changes have been made if you care to take another look.

I also left out many of the stax staples that are in many alesha decks in the effort to provide some added fairness.

This deck is good stuff. I think that your weakest card is likely Avalanche Riders. If you're gonna go land destruction then you should have a bit more of it in here than just a few cards. I would recommend putting Erebos, God of the Dead and Archetype of Aggression in there, give you some control over green and white.

What are some other land destruction cards I should consider? I had armageddon and would fit that in again if I could think of a cut.

I would recommend Ruination, Volcanic Upheaval, Dwarven Miner, and Dwarven Blastminer. This is really just personal opinion, I like ETB effects but I like to have cards that can destroy lands repeatedly. I wish you could run Deus of Calamity because that one is a beast of a card.

cool. think I have a dwarven miner already. thanks again!

Honestly, I can't think of anything to do with this. The best I can think of is Berserkers' Onslaught Just to add some extra damage, maybe Leyline of the Void to counteract some graveyard shenanigans...Other than that this seems like a brutal deck. Well done.
