Rograkh, Son of Rohgahh / Thrasios, Triton Hero

How it plays & wins

This is a blue-green creature-based midrange deck with a heavy fast-mana and free-interaction package. Rograkh and Thrasios open the game with a mana dork or a Mox, Sol Ring, or Mana Vault. Rhystic Study and Mystic Remora generate card advantage, while Force of Will, Fierce Guardianship, Pact of Negation, Swan Song, and Flusterstorm protect the plan. Green Sun's Zenith, Chord of Calling, Worldly Tutor, Gamble, and Crop Rotation find whatever the position needs.

The most likely win is a storm finish with Underworld Breach. Breach with Lion's Eye Diamond is a known engine, and Brain Freeze can then be cast repeatedly to mill an opponent out. Beyond that, the list has no other combo I can confidently describe. Creature and mana pieces like Gaea's Cradle and Urza's Saga could apply pressure, but a clear second route isn't obvious from the list.
