Leyline of Sanctity + Sky Swallower + Fractured Identity + Lier, Disciple of the Drowned

Leyline of Sanctity

Sky Swallower

Fractured Identity

Lier, Disciple of the Drowned

How it works

1. Cast Fractured Identity by paying 3, exiling Leyline of Sanctity and causing each opponent to create a token copy of it.
2. Cast Sky Swallower by paying 3.
3. When Sky Swallower enters, it triggers, but you cannot target an opponent as they all have hexproof.
4. Cast Fractured Identity from your graveyard for its flashback cost by paying 3, exiling Sky Swallower and causing each opponent to create a token copy of it.
5. When each opponent's Sky Swallower enters, they each trigger. Each opponent is forced to target you, as all other players have hexproof, giving you control of all their other permanents.
