Castform (Sunny) ranks #101 of 1154 in Great League, with a PvPoke score of 86.3 (tier B). That’s its best league of the three. Rank reflects the whole meta, so check its moves and what it beats before you build one.

Run Ember with Weather Ball and Solar Beam. That’s PvPoke’s recommended Great League moveset for Castform (Sunny).

Great League, where it scores 86.3, its best among Great, Ultra and Master League. Scores are relative to each league’s meta, so your IVs and Stardust budget can still point you elsewhere.

No. None of its recommended moves are legacy moves, though you may still need regular TMs and a second Charged Attack.

Getting a legacy move back takes an Elite TM, an event or another special method, and some can’t be taught with an Elite TM at all. Check the move before you spend one.

These IVs maximize Attack × Defense × HP under the league's CP cap and the calculator's level limit. They are a useful starting point, but matchup breakpoints and Charged Attack priority can favor other spreads.

In Great League, Pokémon that can exceed 1500 CP often benefit from lower Attack IVs, which can leave room for more total stats under the cap. The exact best spread depends on the Pokémon; it is not always 0/15/15.

The same principle applies to Ultra League's 2500 CP cap. Pokémon that cannot reach the cap at the allowed level generally benefit from higher IVs in all three stats.

Master League has no CP cap, so 15/15/15 maximizes a Pokémon's stats at a given level. Some other spreads perform similarly in particular matchups.

Run your own Pokémon through the IV checker before you spend Stardust. The rank 1 stat product is a good target, but breakpoints and bulkpoints in the matchups you care about can make another spread better. PvPoke’s simulations don’t necessarily use the spread shown here.

Base second Charged Attack cost: 75,000 Stardust and 75 Candy.

Level and Candy XL figures are for the rank 1 build shown. Power-up costs depend on the level you start from. Second Charged Attack costs are base costs; Shadows pay more and Purified Pokémon pay less.

Matchup ratings are out of 1,000. 500 is a tie, and higher is better. A dash means there’s no rating for that matchup.

The overall ranking blends several roles, but key wins and counters come from PvPoke’s lead scenario with two shields each. Treat them as typical results: IVs, energy, shield use and baiting all swing real matches.

Each number is how many Fast Attacks you need before the next throw of that Charged Attack. The first count starts from zero energy. Later counts include the energy left over from the last throw, up to the 100-energy cap, which is why they can drop. Time to first charge counts Fast Attack time only. Switching out or overfarming changes the sequence, and a dash means the move can’t be reached.

Compare energy generation, damage per turn, and attack duration. Faster energy gain helps reach Charged Attacks sooner, while shorter Fast Attacks offer more flexibility. The recommended move depends on the Pokémon's full moveset and matchups.

Power, DPT and DPE on these cards include STAB and the Shadow bonus. EPT is energy per turn, and a turn is 0.5 seconds. Real damage depends on the opponent.

Charged Attacks cost energy to use, deal a large amount of damage, and some of them even have Special Effects that can change your or your Opponents stats.

Charged Attack cards show power, energy cost and DPE (damage per energy). Counts use the Fast Attack selected above, starting from zero energy and carrying leftover energy into the next two throws.
