I will note that when a permanent phases out it does not leave the battlefield and it is not in the Exile zone, and we might want to review phasing rules before using deciding to use it or not (also it doesn't cause memory issues with EoT abilities, it ceases to exist so they cease to affect it... unless they specifically affect phased out objects).

Phasing would actually be really interesting since there are things you can do with it that haven't been done (cards to interact with it, which would need to be kept at a minimum due to parasitic effects, enchantments with different effects whether phased in or out, etc), but is typically considered to have been a bad mechanic from what I've heard and is one that most people don't remember the rules to. It'd also probably not be best to bring it and flip cards back at the same time, so we'd probably want to choose one or the other.
