Hi fellow Mono-R players. I placed 3rd at a local Legacy for Staples event this weekend, and I wanted to share some of my experience playing the deck in the event.
The list I ran is here:

3. Turbo Depths 2-0
G1: I land an early trinisphere followed by a blood sun. Karn comes down and makes two fattys to close out the game.
G2: I get a turn 1 sun into a turn 2 chalice for 2. My opponent resolved a turn 2 Bob that reveals another bob, abrupt decay, and land. He plays a seal of primordium into my chalice instead of the abrupt decay first and scoops when he realized his mistake.
