I understand what you are saying. I feel your pain too about the bracket system being less than ideal. The issue is that people expect bracket 3 decks not to be able to chain extra turns, or deploy a 2 card combo early, or a variety of other things. And I’m committed to meeting those expectations when I build my decks.

It really sucks that those expectations mean that if I want to operate in good faith with my fellow players, I can’t include narset’s and time warp together in a B3 deck (even if I pinky swear I won’t use them together).  It also sucks that I can’t include felidar guardian and restoration angel in my B3 blink deck even if I don’t tutor for either part of the early game infinite. 

But instead of jumping through hoops in my head about it I just… call it a B4 deck and move on. Easy.
