Sharuum beat-down deck focusing on blink synergy. I don't want to be that annoying guy with the combo deck which is why I went the beat-down route. However, if combos are allowed / not discouraged, the sideboard can turn this into a combo deck using Sculpting Steel / Phyrexian Metamorph infinite combo with Disciple of the Vault, Bitter Ordeal, or Glassdust Hulk. Also, Grand Architect + Pili-Pala can make infinite mana.
There are lots of great cards I want to add, but WHAT SHOULD I TAKE OUT??? I really need tips, so please give me advice!
Maybeboard is a mixture of "maybes" and a wishlist of cards I can't afford yet. If an expensive card is in the deck, that's because I deemed it essential or I already own it. Super pricey cards like fetchlands are just out of the question. I'm not made of money.
Have you think about using Unburial Rites ? I'm thinking of building a Sharuum deck myself, would you recommend it?
I might consider it for a budget Sharuum deck, mostly because the flashback makes it useful if it enters your graveyard through Nephalia Drownyard or similar. However, even then I'm not sure I would include it simply because it doesn't add anything you can't already do. Sharuum herself cheats artifacts from the graveyard, and as your commander you should have access to her as much as you want. With sharuum out, a blink card can have pretty much the same effect as Rites, and probably for less mana.
So, short answer: probably not, because its effect is redundant compared to Sharuum's.
