Barbara Wright + Myojin of Grim Betrayal + Summon: Knights of Round

Barbara Wright

Myojin of Grim Betrayal

Summon: Knights of Round

How it works

1. Activate Myojin of Cryptic Dreams by removing an indestructible counter from it, putting Summon: Knights of Round from your graveyard onto the battlefield, and choosing to have it enter with five lore counters on it due to its read-ahead ability.
2. The Summon: Knights of Round token's fifth chapter ability triggers, causing creatures you control to get +2/+2 until end of turn and putting an indestructible counter on each of them, and then causing you to sacrifice the Summon: Knights of Round token.
3. Repeat.
