Master Ball
Master Ball! but if you dont have it, just use dusk ball at nite.
master ball
No, you do not use Cobalion, Terrakion and Virizion in order to summon Keldeo.
weaken lugia down till it is almost dead than use a poke ball you will not catch it but then use an ultra ball and then you have lugia. PS. use the master ball on entei
The hardest 5 Pokemon to catch in the game are: Cobalion, Terrakion, Virizion, Tornadus, Thundurus, and Landorus. All of them have a catch rate of 3, and are probably the ones you should use your Master Ball on. Do not use it on Reshiram/Zekrom. It's a waste of a Master Ball, because they both have a catch rate of 45. It's much easier to go after them with an Ultra Ball.Technically, you can catch all 5 of the ones I listed with an Ultra Ball, (like I did,) but sometimes it's just easier to use a Master Ball on them and call it a day. It's up to you, really.
Any
you should use it on lugia. he is the hardest one to catch. you cant catch him with any other pokeball. you can only catch him with a master ball.
Master Ball
The best ball to catch Deoxys is a Master Ball or a Timer Ball! Trust Me!!! Pokemon Master
You should use a Master Ball or a ton of Ultra Balls and you might get lucky.
