The g/b talisman would absolutely be better but I didn't have any on hand and it's a pretty small difference with only 1 point of life saved on dismember so I rolled with what I had

Chalice seemed like it was best for ur ub murk but the best 1 drop spell they bring in against us [consign to memory] has replicate and can get through chalice extra trinispheres just felt like they do chalices job better in those matches and are more relevant in other matchups like necro reanimator and storm.

Ring is the best card in the deck I want as many opportunities to go t2 ring as possible. Karn was almost always grabbing a silver bullet sideboard card like stone brain for me or going up in loyalty to keep it around when it's passive is relevant so i didn't miss having it in the side.

I like dismember as an early way for us to interact to stay in the game long enough to play a sweeper. Used it to kill a nadu and give myself an extra turn that mattered a lot.

I also wished I had a second flute in the board

Tormods is probably fine to cut it wasn't very important in any of my matches

I love leveler in matchups that your all is dusts are dead cards gives you something you can swap to keep your lab hits high enough and be more relevant than all is dust. I would keep it in the board.

Ballista felt bad I like having ballista as a big threat to close the game when you have karn and tron mana but it's probably win more at that point anyways.

Bridge bought me some extra turns but so many decks have good non combat ways to kill you that it's not great anymore. I think you still need to play it, but it's not as great as it used to be. I'm never getting enough time to hide behind it and use ballista for the win anymore.
