Articles on catching MewTwo?

You don't need to.

Here are my tips despite i don't have an ex raid pass:

* Keep your cool and remember it's just the same as a tier 4 boss.
* It is far away so throw a bit farther. I think the Groudon or Gengar distance is the right one.
* Lock the circle until it is the size of its head and curve ball; Aim for the head.
* Gold razz it at all costs.

Show up early, and take control of the gym if your team isn’t already in control. He’s not hard to catch, you just have to be patient. DEFINITELY stock up on gold berries. That, and gym control, makes catching him a near certainty.

Also, aside from Mr-ex777 and urbanhoustonian have mentioned, try to group with other participants by color. This is extremely important. Secure 10+ balls, you will.

Except i threw on my 3rd mewtwo all GR 8 excellents and 2 great throws with curve still ran away so that kinda bs can happen still salty after 2 weeks.
