let me refer to magic, where similiar things can happen.
its resolved via "time stamps"
the last played card trumps

its still a headache there

That's because you skipped "layers"

possible. i tried to understand the mechanic at one point but gave up on it.

yesterday i encountered 2 global effects in trek that cancel each other out, but i forgot what it was.
maybe time to introduce the last played trumps mechanic?
