Mirkwood Tideshapers

Mirkwood Tideshapers looks like a Simic (Green-Blue) creature-based midrange/synergy deck built around Elves, woodland value creatures, and board development.

Its plan is likely to ramp and fix mana with cards like Wood Elves and Mirkwood Nurturer, then curve into efficient synergistic creatures such as Thranduil’s Company, Mirkwood Pathmaker, and Woodland Weavemaster to build a wide, resilient board. Blue cards like Elven Raft-Steerer and the “Tideshapers” theme suggest tempo, evasion, or battlefield manipulation, helping the deck push damage through or outmaneuver blockers.

Overall, the deck probably wins by developing a strong board of synergistic Elves and forest creatures, generating incremental value, and attacking with a growing team rather than relying on a single finisher.
