In a multiplayer game, Anna controls
Withengar Unbound, and Bob has gained control of a
Blood Tyrant whose owner is Chuck. Then Chuck loses the game, causing the ability of
Withengar Unbound to trigger, and Dora wants to
Stifle it. The question is: Has the ability of Chuck's
Blood Tyrant triggered too (under control of Bob)? In this case, Anna could
Redirect Dora's
Stifle to that ability.
I find it hard to tell, because CR 800.4a states that Chuck and his
Blood Tyrant leave the game at the same time, and it also makes clear that these aren't state-based actions. Also, “losing/leaving the game” is a transition, and the question is, whether the leaving object is considered to be on the battlefield during that transition or not. It would be easier when CR 104.5 would describe a two-step process: first, a player loses the game (allowing abilities to trigger), second, this is transformed into the consequences (the player and his cards leave the game). But to me, it doesn't look like that.
I couldn't find similar cases. The closest match I can think of is a 0/0 creature with a +1/+1 counter that gets a -1/-1 counter. State-based actions will remove the counters and put the creature into the graveyard at the same time, but it's enough to satisfy the triggered abilities of
Necroskitter and
Blowfly Infestation. However, these are state-based actions and zone-change triggers with their own special rules.
Any help is appreciated. Thank you.
Kind regards,
