When your trying to figure out how to play with trench run ask yourself this.
Does interpreting the rules this way make trench run a playable card? If yes, then your misinterpreting the card and use the opposite ruling for the duration of play.
FFG designed a card that broke a lot of rules for relatively no reason... out side of RP. The card adds a lot of confusion because we interpret most cards literally were in this card because of the "it is but its not" condition we have to go through each scenario and ask ourselves does this apply to 1 pool or the other. Its a bad card though, dont play with it and that solves a lot of the rule issues.
It feels good under my bridge right now, nice damp and out of the sun.
