1 Cut brings me down to a clean 330 for CubeCon, and I'm concerned my altered Rancor might get flagged because the painted alter is a little thick

Chainsaw felt too good due to the number of tokens on board.

Goldvein Hydra will come back in after CubeCon, but the treasure ramp felt too out of place compared to the rest of the cube

I am adding blue cards to support a small flash and a small clone package, which I am hoping will increase blue's win rate.

Siege Veteran and Ornery Tumblewagg proved to be too good when played on turn 3.

Auriok Salvagers and Sai are cards I'm cutting for CubeCon but will add back later.

Serendib Efreet is a favorite of mine but a kind of boring stat monster so I cut it for now.

Smirking Spelljacker was too swingy but I may test it more after CubeCon.

Whirlwind Denial was blue's worst counterspell.

Profane Command, Curse of Shallow Graves, and Scavenged Brawler are being cut for CubeCon because while I don't think they are too strong, I think it can be unfun to lose to them if you only get to draft this cube once.

Keen-Eyed Curator was both way too strong of a hate piece and way too easy to turn into the biggest card on the battlefield.

Elixir enabled deck loops too easily

Every part of Fanatic of Rhonas is pushed just a little too far in every direction. Being a 1/4 instead of 1/3, tapping for 4 green instead of 3, and eternalizing for 4 instead of 5 or 6 makes this almost impossible to every interact with this card profitably outside of immediately exiling it.

For Season of Loss, I underestimated how strong the flexibility of choosing how many creatures you can sacrifice would be. I had thought of it as a wrath variant, but being able to push your advantage if you're ahead on board made this card feel oppressive.

Dina DNA is too good.
Bloodbraid Elf and Dermotaxi are too weak.
The other 3 just aren't particularly interesting so I'm testing some other cards

Cutting the cards that interacted with lands because I didn't like the play patterns. Also didn't realize Mechtitan Core specified that it had to be artifact creatures which made it too narrow
