Does anyone know how much delta and anceint balls increase the odds by when used properly?

I think Ancient Ball can catch any legendary without fail.Dunno bout delta ball.

Ancient ball is not that good. I’ve used it on many legendaries.

Yep it took me about 50 anceint balls where a good 20 of those where asleep to catch rayquza

Heavy balls are the real legendary catchers and are honestly overpowered as hell if we’re looking comparatively. A legendary has a .3% unaltered chance of being caught. Almost all pokeballs function off multiplying that chance(Ultraball is x2 for example) Heavy ball says ■■■■ that and just gives you a big fat flat number. So chucking an ultraball at a full health groudon is a .6% chance of success, chucking a heavy ball at one is 40.3%!!!

Ive caught giratina, groudon and zygarde in three balls or less after taking them to red and putting them to sleep
