Team building with latios for ML
I recently got a shiny 98 latios (14 hp, I also gave it luster purge). It is one of my favourite Pokemon and i was really excited to use it in the master league, but i am having trouble with team building and all the teams i build and either lose to a zacian or a lunala/yveltal.
I think metagross could be a good pairing as it counters both zacian and lunala. But the 3rd pokemon is what i am unable to settle on.
I would appreciate any feedback or team ideas.
Below are all the pokemon i have at lvl 50 and built for the ML.
1)Black kyurem
2)White kyurem
3)Palkia origin
4)Kyogre
5)Dialga origin
6)Groudon
7)Reshiram
8)Lunala
9)Zekrom
10)Garchomp
11)Ho-oh
12)Latios
13)Xurkitree
14)Metagross
15)Yveltal
16)Xerneas
17)Keldeo
18)Lugia
19)Melmetal
20)Excadrill
(I also have a lvl 40 lucky zacian 12/14/15 and a lvl 40 zamazenta 12/15/15 which i got from a lucky trade, i was taking a break from the game when they released so these are the best ones i have)
