Mega Effects

Mega Effects are special skills in Pokémon Shuffle. These skills are activated upon matching a Mega Evolved Pokémon. A Pokémon can Mega Evolve if the player has the appropriate Mega Stone and matches the Pokémon enough times, represented by the Mega Gauge. Only the player's first Support Pokémon can Mega Evolve, meaning it is only possible to have one Mega Effect at a time.

Each Mega Effect can either erase or replace Pokémon icons and in the puzzle area. The kinds of tiles targeted differ depending on the effect. If the Mega Effect erases icons, each non-empty tile that is erased boosts the amount of damage dealt to the opponent. If a Mega match and at least one non-Mega match are made simultaneously and have equal priority, the Mega match will activate last.

Mega X and Mega  X, as well as the Shiny variants of both, will change type from Psychic to Fighting or Fire/Flying to Dragon, respectively, upon Mega Evolving. If the player has obtained one of those Pokémon and both of their respective Mega Stones, they will have separate entries in the Pokémon list for each Mega Stone. Only one of each may be used as a support Pokémon; EXP and Skill levels are shared between them, but Mega Speedups are not.

List of Mega Effects
The table below details for each Mega Pokémon: its Mega Effect, the default size of its Mega Gauge (the number of icons that must be matched for the gauge to be filled), and the maximum number of Mega Speedups that can be used on it (reducing the size of the Mega Gauge).

In the event of a damage boost, it will be affected by and skills affecting combos, such as Ice Dance.
