I am currently battling a Pokemon that doesn't want to be caught called Cresselia. I wanted to know what kind of Pokeball I should use to try and catch it. I'm pretty sure it only has a HP of 1 and it is a female. It it only possible to catch it with a Master Ball? As per usual, Thank you to anyone who answers!
If you don't want to use your masterball then I would suggest using Ultra Balls. Lower Cresselia's HP and then paralyze it.
Spam Ultra balls until you catch it. It has moonlight so having a Pokemon that can learn Taunt is a good idea.
