Technically, if the proposal you are referring to fails, then it won’t be in the queue at the time this proposal is resolved; which means “this proposal does nothing” will not trigger.
(In other words, a proposal is always the first in the queue at the time it is resolved, therefore there are no proposals before it, and using the past tense for “failed” doesn’t change that.)

After some thought,  .

While it seems a little anticlimactic to have a tame pseudo-time travel mechanic after the craziness of a real time travel mechanic, I realized there’s actually some potential here. Each Era could have its own rules, which apply to that Era and all the ones after it. Meanwhile, a Era could repeal a past rule in its own time, which ripples into the future. Say, past says A, but rule B in the present makes it situation C in the future.

Akin to M:TG’s Time Spiral block, I’m thinking, the Past could have some mechanism for extracting past rules from past rulesets, the Future has “futureshifted” rules (rules that might theoretically be in a future dynasty) and the Present has no restriction. This is all imagination of course, right now it’s way too late for me to write a proposal.

Am I misunderstanding something? If the previous proposal fails, then we still have all of the Time Monk dynasty-travel rules in place, so don’t need a new time travel mechanic on top of them.

Also “Time Monks may occupy an Era” sound like it’s not mandatory to occupy an Era. Are some Time Monks out of time?

CoV, must have just misread that clause.
