Will Trick Transport defeat Danger Seeker?
The second part of the text for Danger Seeker says, "or cannot be attacked." - so if I play Trick Transport on Grunge, and it lands, then Danger Seeker would have to go away, right?
Yes.
It goes away because terms are met? Would What happens if puppet master, maurauders or task master play it with BQ ? Does it go on player or back to grunge?
Related question: what happens if hawkeye action leader puts grunge in reserve. He CAN Still be attacked it's just hard to do: AoA shadowcat can attack him, spawn with FZ, Punisher with AN or would that also make seeker go away?
