Hate to break it to you but marvel and timepiece aren't a combo. - Permanent means literally any card on the battlefield it doesn't count any form of mill ( putting card from library into the grave). since this is a casual deck - I'd toss in the artifact lands so you have sac fodder late game and to fuel the affinity cards :Ancient DenSeat of the SynodVault of WhispersGreat FurnaceTree of Tales
To ramp energy - i'd suggest running the puzzleknots over elixer and time piece. as they'll give you 6 energy when cast and sac while giving you other value.

also add a few poison guys in since you can proliferate thier poison counters for a win.

Thanks for catching that timepiece thing, disappointing. I'm not going to be putting any poison in as I don't find that a fun way of winning. (exception of blightsteel colossus because getting the creature out is fun and it isn't too hard to remove.)
