Based on a MrLuBuFu's build of the Time Warp deck, this is a brew I've been working on.The idea is to draw a lot of cards and play a lot of lands with Rites of Flourishing and take a ton of turns with Time Warp, Temporal Mastery and, when you have a lot of lands in play, Walk the Aeons with buyback.

The wincon is to mill your opponent with Jace Beleren or yourself with Laboratory Maniac in play. Yeah, it's a durdly deck.

I've been experimenting with Leyline of Anticipation and it's been surprisingly good. You can keep untapped lands to counter their threats and, if they don't play anything worth countering, you can drop the Rites. And you get the effect first!

I'm very open to suggestions, I haven't been able to test this very thoroughly, but I've had a lot of fun playing with it! :)
