Ramp hard, draw relentlessly, and turn every land drop into an advantage. Aesi, Tyrant of Gyre Strait rewards you for doing what Simic does best: playing lands and generating absurd amounts of value. With a huge suite of ramp spells, landfall creatures, and utility lands, this deck quickly grows from a few harmless land drops into an overwhelming board state.
Play lands. Draw cards. Make monsters. Repeat.
