Choose the right kind of target
Look at the entry’s role first. A starter candidate, a configured League member and an evolution form are different records. For Gengar, the relevant starting entry is Gastly.
A Pokémon missing from this small preview has no reviewed companion page yet. That alone does not tell you whether it exists in the game.
Check every listed condition
Use the original game’s challenge display as the source of your personal progress. Pikachu lists a rain-defeat counter. Gastly requires elemental reactions in one run. Eevee requires both League membership and distinct Pokémon played.
The tracker stores only what you manually record. Leave an uncertain condition unmarked. The preview does not read your account, validate counters or simulate the server.
Keep capture separate
A challenge being met is not proof of an encounter or a capture. The configured League flow includes a later encounter and capture stage; this preview cannot guarantee when a target will appear.
Only record a capture after you confirm it in the original game. Alpha support belongs to the current run and must not be counted as a permanent League addition.
