Whenever Dragonlord Ojutai deals combat damage to a player, look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in any order.
Resolve Dragonlord Ojutai, protect it with hexproof while it sits untapped on your turn, then swing for 5 evasive flying damage that both advances your clock and digs you toward answers and threats. The deck plays as a UW control/tempo shell that stabilizes the board, builds card advantage off combat damage, and grinds opponents out before closing with the air or a big finisher.
Built-in protection: hexproof while untapped dodges most spot removal and forces board wipes or instant-speed tapping
Strong card advantage engine that snowballs once connecting in combat
Evasive 5-power flyer wins races and pressures planeswalkers/players quickly
UW control gives access to the best wraths, counterspells, and stax pieces
Vulnerable when attacking (tapped = no hexproof), so attack steps invite removal
Board wipes still kill it; you must rebuild card advantage from scratch
Slow against fast combo and go-wide aggro that ignores a single flyer
UW lacks ramp and card draw outside of Ojutai itself, leading to clunky early turns
