Ex Raid Prep and Tips.
Be ready for a fast and long battle.
Long in terms of getting the gym.
Fast in terms of getting Mewtwo.
Get to Your Ex Raid atleast 1 to 1 and half hours early, if you want gym advantage. Come prepared with golden razz atleast 20 or more.
Once you have gym control only berry at the last moment to get full advantage of healing.
Once the battle for Mewtwo begins, it generally lasts 2 minutes, if it’s a full room. Yeah all that waiting for a quick raid. Be sure to be on time cause missing a spot could mean missing Mewtwo
Take deep breaths think of something other than Mewtwo when throwing, i have seen numerous trainers miss Mewtwo due to stress and overthinking. Just think of it as a Pidgey or anything other than it being Mewtwo.
