Dies to Removal

And extremely fragile. I've got an Edric deck built. It's not as strong as I was led to believe.

Yeah, freedom's got it. Before you even place triggers on the stack, one of the Sharuums dies. So yes, she can target herself with her own ability.

Oh dear, I screwed that up. No sac outlet for this one. All it does is give you infinite enters/dies triggers. However! The new rules actually help a lot since any Clone can let you combo off.

Sharuum in play, play Clone.
Sharuum (original) dies to legendary rule.
Return Sharuum to play with Clone's ability.
Repeat.

Your primary wincons then are Disciple of the Vault, Blood Artist and Falkenrath Noble (with Vela the Night Clad and Dire Undercurrents as backup). So much redundancy.

Sharuum has the same combo with Sculpting Steel, but you have: 1) More redundancy (Phyrexian Metamorph), 2) A general that pulls the combo pieces back out of the graveyard for you, and 3) Access to blue. The deck as a whole is getting very close to strictly better than Teysa. Plus you don't need your sac outlet to necessarily even do anything if you've got a Disciple of the Vault or similar on the field. The only downside is that it's succeptible to graveyard hate, something Teysa dodges a little bit (she still gets hit by Leyline and RIP).

You should probably just choose one or two of those rather than try to do them all. Infinite combos mixed with land destruction seems bad.

Sharuum combo is extremely powerful, for the record.
