Etrata, Thief of Sanity

This is an Etrata deck main board with a lot of disruption to make sure the opponent can't deal with her. Thought erasure, negate, blink of an eye deal with single threats while ritual of soot deals with tokens and early-game boards and mission briefing lets us replay these cards. Mausoleum of secrets helps search for Etrata. Nightveil predator is a secret tech of the deck that works as a way to keep flyers from getting the best of us plus they have hexproof, which makes them harder to deal with unless they block with their flyers. Also note that predators live through ritual. The sideboard is literally meant for non-creature and control match-ups to where we take out Etrata and replace her with thief of sanity as our main win con. Sideboard also has a lot of cards that just keeps control even more in check.
