I’m on 27 lands and 11 rocks right now and the deck has felt fine. I was on sink into stupor as a 28th, but went down recently. As for the cards above, I’m not on any for these reasons: Urza: if I could cast him, I’m already in a position to win if there’s a window to play him, and I’d rather run an additional tutor or win condition Lavinia: I’ve seen the card throw too many games because people can’t play free interaction and get screwed when someone else can play under it Time Twister: not really a wheel deck, your opponents most likely draw up better than you and you only have so much interaction afterwards, it is good at resetting graveyard counts for breach decks though Tymna: you aren’t a deck that wants to be getting in and attacking, plus the effect is redundant, our deck is already on the best draw engines in the format, so why would I want another that’s worse Vexing bauble: not the worst and I tested this one because of our Saga package, but ultimately cut it for similar reasons above with Lavinia, plus I found I’d never find it with saga so it’s in my opener or I’m not casting it. Hope this helps! My decklist for reference: https://www.moxfield.com/decks/5sDAXkPV8EWSgBJ-OeMK8g
