Azorius GenericBlink wins by flooding the board with small creatures through Ocelot Pride tokens and Guide of Souls triggers, then generating insurmountable card advantage via Ephemerate blink loops with Phelia and Starfield Shepherd. Trinisphere is your most impactful sideboard card here — it taxes Ephemerate, Guide of Souls, and evoked Solitude up to three mana each, completely disrupting the tempo engine that makes this deck tick. Unholy Heat and Dismember give you targeted answers for priority threats like Phelia and Quantum Riddler that would otherwise generate persistent value if left unanswered. We trim top-end redundancy since one resolved Emrakul, the Promised End is typically enough to close out a game that has stalled, and Sire of Seven Deaths and the extra Ugin copies are the least necessary in a race where your ramp engine should carry you past their threats. Keep one Kozilek's Return as a sweeper safety valve against a wide token board from Ocelot Pride.
