Yes Merrick, I understand why GEMP exerted Merry, I just don't agree that it is the appropriate interpretation of the site text. There is nothing in the rules that spells out what AND really means in a situation like this. It may be a unique situation for all I know.
You are arguing that the game text is split into 2 evaluations, and I am arguing that the game text is a single evaluation for each character. Kralik spells it out perfectly with the code above. Without a ruling on what AND truly implies, I can only assume it means "at the same time" since there are other cards that specifically use the word THEN to indicate a series of actions. If the Bog was truly a series of two checks I would expect it to also use the word THEN.
Since I am arguing that the entire site text is applied to Merry at one time, then his resistance doesn't change until after I've already applied the site's game text in its entirety. I can't apply the game text a second time to exert him because "when" actions can only happen once.
It's clear to me that this isn't a "bug" so much as a difference in interpretation of the game text.
Just admit that if you were playing in real life, not thinking in sequential code language of a computer that can only do literally one evaluation at a time, that you would not have exerted Merry
I'm sure most people in real life would not have.
