Missed triggers at Regular REL
This coming Saturday I will be judging at the Prerelease. Of the five new guild abilities, four of them involve triggers. Of those four, two say “may” and two do not. I'm already anticipating hands going up calling “judge” for any one of those triggers getting missed. I've read the IPG section many times on missed triggers. But, as documented, the IPG is not for Regular REL. I've read the JAR many times, too. Triggers aren't mentioned there, but “required game actions” are, and they do make mention of actions that were optional, saying to play on as if they were opted out.
Events at Regular are for fun, sociality, education, and yet there are prizes involved. For lack of clearer documentation on the subject, my initial reaction to missed triggers at Regular REL is to give the player a turn to recognize a missed trigger they control, whether it says “may” or not, and allow them to put it on the bottom of the stack. Opponents are also responsible for game state at Regular, but I don't hand out Warnings for those, even if they're detrimental to the controller. I think I would only do this if I detected the player was trying to get away with something over and over again.
So, my question is two-fold: 1) Are there any documents or articles addressing missed triggers at Regular REL and 2) have I been handling this correctly in the past? I want to be a good Level 1 and I want to be prepared to judge the upcoming Prerelease.
