New Commander PW :

Estrid, the Masked - 1GWU
Loyalty: 3
+2: Untap each enchanted permanent you control.
-1: Create a white Aura enchantment token named Mask attached to another target permanent. The token has enchant permanent and totem armor.
-7: Put the top seven cards of your library into your graveyard. Return all non-Aura enchantment cards from your graveyard to the battlefield, then do this also for Aura cards.
Estrid, the Masked can be your commander.

Her +2 really helps to cast Emrakul.
Her -1 can protect your lands against Wasteland / Ghost quarter. Or your drawing engine, or lock pieces.
Her ultimate gives you around 4 enchantments in play

She is a Candelabra-Sterling grove-Replenish PW :)

Unable to protect herself, but serious potential here !
