One ruling from Wizards of the Coast
- 5 February 2021The Angel or Berserker doesn't have to still be under your control in order to activate Cleaving Reaper's ability. Additionally, the Angel or Berserker could have entered the battlefield under your control at any point in the turn, even before Cleaving Reaper was put into the graveyard.
