I wanted to toss a smattering more self-exiling cards in the set to help the clean graveyard theme along. Since I wanted it to feel natural, I figured a permanent that takes extra turns would make sense, since recursion would make this card overbearing if it didn't include the self-exiling line. For the card to have some extra legs outside of Time Warp, I also gave the option for any color to use it at a cost by using the already established 3/H (though, the ability to activate this between two player's turns in a group game should be reason enough to play with it).

Works better with Rings of Brighthearth than Time Warp does :3 (Although I guess Time Warp works better with Mirari, so they cancel out.)

Also works better with Sculpting Steel and Phyrexian Metamorph. (But not Reverberate or Dual Casting. OK, I guess they're still balanced.)

This does look quite expensive for what it does, though.

Also works with Ibok, Neurok Engineer ;)

It is expensive for what it does... but I think I can shave off the activation. Now it has some nice repetition of the number 3, costs in one go, or split over two turns... that seems fine. I'm pretty sure that if I made it cost 3 and 3, it would just be better than Time Warp.

Nice. Looks good.
