How to Evolve
Y Seadra Best Moveset
MoveSurf and MoveBlizzard from 95 Special hit solidly in the mid-tier, and 85 Speed goes first against a fair chunk of the competition. Not the power of Starmie or the bulk of Lapras, but the Water/Ice coverage works against most neutral targets. Fills the middle ground competently.

Moves List
Without TMs, Seadra's movepool is bare bones. With them, you get Normal and Ice coverage on top of Hydro Pump and Surf for STAB. The natural kit handles basics, but TMs are doing the real work.
