I have a question regarding Kathril, Aspect Warper's ability. The ability is as follows:
When Kathril, Aspect Warper enters the battlefield, put a flying counter on any creature you control if a creature card in your graveyard has flying. Repeat this process for first strike, double strike, deathtouch, hexproof, indestructible, lifelink, menace, reach, trample, and vigilance. Then put a +1/+1 counter on Kathril for each counter put on a creature this way.
Now, as I understand it, this ability is a triggered ability that is put on the stack when Kathril enters the battlefield (so the spell "Kathril, Aspect Warper" has resolved). This means any player can immediately react to this trigger, before it has resolved. This has led to some confusing situations regarding the creatures that receive a counter.
The part that confuses me is this:
put a flying counter on any creature you control
According to rule 115. Targets:
115.1d A triggered ability is targeted if it identifies something it will affect by using the phrase “target [something],” where the “something” is a phrase that describes an object and/or player. The target(s) are chosen as the ability is put on the stack; see rule 603.3d.
This is not a target-ability since it does not state "target [something]".
- So what is this ability then?
- Do I need to specify targets as soon as the ability is put on the stack?
- Can the chosen creatures be changed by something like Willbender?
- Is there even a moment opponents gain priority between Kathril entering the battlefield, en putting counters on creatures?
Question 2, 3 and 4 matter quite a lot when you want to make Kathril hex-proof and indestructible, but an opponents wants to remove Kathril before the trigger resolves.
Any info or relevant rules would be greatly appreciated.
