what moves are very effective to seadra
Disable is Seadra's main niche, and Seadra has the power and Speed to pull off a SubDisable set. Switch into a Pokemon that Seadra forces out, set up a Substitute, and use Disable to play around the opponent's next switch-in. Seadra is very bulky on the physical side, allowing it to take hits from physical attackers, disable their main STAB move, and force them to use a weaker move that does not threaten it.
