- 25 August 2015Players can respond to the triggered ability, but once it starts resolving and you decide whether to pay {4}{R}{R}, it's too late for anyone to respond.
- 25 August 2015The landfall ability triggers only if Akoum Firebird is in your graveyard at the moment the land enters the battlefield.
- 25 August 2015If, during its controller's declare attackers step, Akoum Firebird is tapped or is affected by a spell or ability that says it can't attack, then it doesn't attack. If there's a cost associated with having it attack, its controller isn't forced to pay that cost. If they don't, Akoum Firebird doesn't have to attack.
