Ozai the Phoenix King, when cast on Main Phase 1 with two untapped lands skips to declare attackers steps immediately upon resolution. After declaring him as an attacker, opponent gains and maintains priority throughout combat phases. There is no opportunity to tap two lands, to get to 6 unspent mana and grant him flying and indestructible. Opponent can declare blockers, and then damage assignment immediately occurs. when combat ends the turn is over - Main Phase 2 is also skipped.

This bug occurred in two matches in the same Quick Draft BO1.
