Why bracket 4? — Optimized

3 early two-card combos: Obeka, Splitter of Seconds + Descent into Avernus, Panoptic Mirror + Temporal Manipulation and 1 more

A two-card infinite combo cheap enough to assemble and win in the early game (data from Commander Spellbook). Bracket 3 decks are expected not to run these; any means Bracket 4.
