Corey Drafter of Accords

At each end step, if no creatures where declared as attacking this turn place a petition counter on Corey Drafter of Accords.
You may remove a petition Counter from Corey Drafter of accords for each opponent and create a legendary artifact token named Declaration Against Battle or D.A.B.
(D.A.B. has whenever the next creature becomes declared as an attacker, instead remove all creatures from combat and tap each creature its controller controls and sacrifice D.A.B.)
