Top Counters for Altered Forme Giratina:

To triumph over Altered Forme Giratina, you’ll need a solid lineup of counters. Data from Pokebattler reveals that the most effective counters include:

10. Origin Forme Dialga: Dragon Breath, Roar of Time

While the aforementioned counters boast incredible potential, not everyone will have access to shadow or mega Pokémon. Therefore, here are ten additional counters that can effectively chip away at Giratina's health:

Team Requirements:

To successfully defeat Altered Forme Giratina, ideally, you'll want at least three trainers to ensure a steady offensive on Giratina. While technically, you can beat it with just two players using top-tier counters, maximizing your CP and strategic play with dodge mechanics like the Circle Lock Technique is crucial. Always use Golden Razz Berries for capturing Pokémon, and remember that catching a Shiny guarantees success—so don’t forget the Pinap Berry for extra candy!

Shiny Chances & IV Calibration:

The probability of encountering a Shiny Legendary Pokémon is approximately 1 in 20—a thrilling chance that keeps trainers coming back. For those seeking the pinnacle of performance, the 100% IV Altered Forme Giratina boasts a Combat Power (CP) of 1931 in standard weather and an impressive 2414 when conditions are enhanced.
