Which Mega Mewtwo form should you choose?
The choice between Mega Mewtwo X and Mega Mewtwo Y involves several elements that must be considered. Among them, the time available to play during Go Fest, the damage potential of each form and the possible specific Adventure Effects stand out. It is essential to remember that the Mewtwo acquired in this Temporary Research will already come with the first level of Mega Evolution active.

For starters, Mega Mewtwo X’s availability in raids is exclusive to Saturday, July 11th, while Mega Mewtwo Y appears in raids only on Sunday, July 12th. To activate Mega Mewtwo X, you need to accumulate the corresponding Mega Energy
Therefore, if the player plans to dedicate more time to the event on Saturday, it may be strategic to opt for Mega Mewtwo Y in the research. This would allow you to accumulate energy for Mega Mewtwo
In terms of raw strength, Mega Mewtwo Y is often considered to be slightly more powerful, but the difference between the two forms is minimal and barely noticeable. Both excel as Psychic-type attackers. Additionally, both Mega Mewtwo X and Y can be used as effective attackers for other types, depending on the charged attack equipped.
For types like Electric (with the Lightning attack), Ice (with Ice Beam), Ghost (with Shadow Ball), and Fighting (with Concentrated Blast), Mega Mewtwo Y generally outperforms Mega Mewtwo X. However, Mega Mewtwo X excels in the Fighting type, especially because it acquires this typing. It’s worth noting that, as a Fighting type, Mega Lucario is still more powerful than Mega Mewtwo X.

Considering all these aspects, the ideal decision will mainly depend on the period in which the coach plans to participate more actively in Go Fest and his game priorities. Both of Mewtwo’s mega evolutions are extremely powerful and valuable, each with their own benefits and strengths.
Information extracted from game data indicates that Mega Mewtwo should have an exclusive Adventure Effect, activatable to obtain special bonuses. However, Scopely has not made an official announcement, leaving it unclear whether the idea has been scrapped or will be launched in the future. Below, the effects that were leaked:
- Mega Mewtwo X with Dynamic Punch: Enables the breaking of two shields in Super Mega Raids for a period of 10 minutes.
- Mega Mewtwo Y with Future Sight: Shows Pokémon with “high stats” before capture for 5 minutes.
Most players will likely find Mega Mewtwo Y’s Adventure Effect to be more advantageous overall. However, for those playing in regions with fewer participants, the ability to break two shields provided by Mega Mewtwo X can make a significant difference, especially if other players also activate this effect. It should be noted, however, that there is a possibility that these Adventure Effects will never be implemented in the game.
