Is Seadra Good in Let's Go Pikachu & Eevee Playthrough?

Seadra has decent Special Attack but can't evolve to Kingdra in Let's Go. Starmie, Lapras, and Gyarados all outclass it in the Water-type competition. Not bad, just outshone.

2 Methods
Fastest Path

The best route is Catch Combo at full boosts, about 1 in 274 on each try. Tune it below.

Step 1 · Encounter Method2 in Let's Go Pikachu & Eevee

Catch Combo: Catch one species back-to-back. A Lure stacks on top of a 31-plus combo.

Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.

How is this calculated?

Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.

chance after N tries = 1 − (1 − p)^N,  where  p = 1 / odds per try

Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.

The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.

These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.

Seadra Weakness

Electric and Grass moves hit Seadra for super-effective damage. It resists 4 types, giving it decent defensive coverage. Seadra's physical bulk (base 95 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Let's Go Seadra Best Moveset

95 Sp. Atk at 85 Speed on pure Water. No Kingdra evolution available, making this the ceiling. Without AbilitySniper boosting crits, the moveset runs special Water TermStab on moderate numbers. Decent pace but outclassed by every Water-type with Mega access or higher stats.
