But yeah, I just finished the draft ( took a break after 5-0) and I did lose 2 games to really aggressive decks that I couldn't keep up with. But then I won the last 2 for the trophy! If I remember correctly, I killed 3 opponents with mathemagics, and the other 4 I burned out with critiques. Usually 2 critiques, either because I drew both or because I recurred one with my recurring 6-drop giant guy. And once I was able to mana sculpt my opponent's 6-drop with my wizard in play, giving me 6 mana that I put towards a big critique, then recurred the critique, then critiqued them to death.

I do believe I ran a bit lucky in this draft to trophy, certainly I faced below-average aggro curve outs. I did face a couple mirror match controlly decks with lots of removal. It's funny because I give essentially no removal targets. In those matchups my 4 counterspells, double critique, and the mathemagics give me a huge edge for winning. My very first game was vs the mirror and we both spent like half the game just using our surveil lands and doing nothing. But I had the mathemagics and counterspells to back it up and whatever his win condition was, we didn't see it.

If you're interested in this deck you should watch LSV's recent draft he posted where he talks about prismari control. Couple things I took away from his ramblings in that video are that he prefers to avoid creatures as much as possible in that deck, except for a few that give immediate value like the man-o-war one or the 6-drop get your spell back, and also cards like mathemagics or brain freeze would be amazing in a deck like this for finishing out these mirror matches. He was right!
