Estrid, the Masked

Sanctum of Eternity

How it works

1. Activate Estrid's second loyalty ability by removing one loyalty counter, creating a Mask Aura token and attaching it to Sanctum of Eternity.
2. Activate Sanctum of Eternity by paying 2 and tapping it, returning Estrid to your hand.
3. Activate all other enchanted permanents that can produce at least 4.
4. Cast Estrid by paying 1.
5. Activate Estrid's first loyalty ability by putting two loyalty counters on it, untapping all enchanted permanents you control.
