3 rulings from Wizards of the Coast
- 22 June 2015If a creature with renown deals combat damage to its controller because that damage was redirected, renown will trigger.
- 22 June 2015Renown won’t trigger when a creature deals combat damage to a planeswalker or another creature. It also won’t trigger when a creature deals noncombat damage to a player.
- 22 June 2015If a renown ability triggers, but the creature leaves the battlefield before that ability resolves, the creature doesn’t become renowned. Any ability that triggers “whenever a creature becomes renowned” won’t trigger.
