I would recommend trying to go far enough into Escalation battles to get the reasonable Mega Speed Ups. Rayquaza is a massive investment, but when you reach him, he makes a WORLD of difference with how absurd his combo potential is.this is the first time i'm attempting to go all the way on an escalation battle. i usually stop at 100. man after level 280 it's pretty difficult. i have to use attack power or risk wasting a heart. team is mega latios / dragonite / zygarde / haxorus. currently at 285 and counting.
in other news, got a thundurus psb every day so far. my reshiram is up to skill level 3, don't know if i should bother any more. in several games i have yet to get a greninja psb; giving up on that. still many days to work on kyogre but i have it up to skill level 2.
as for safari, wasted like 20 hearts so far and haven't found phione. already caught everything else from last time. if i get it then i can start playing mew.
edit: level 300 wasn't too bad. you just have to get it almost done before the disruption kicks in.
I'm up to level 215 and climbing, managed to go itemless except on the "boss" stages for the most part using a team of Rayquaza, Zygarde 50%, Goomy, and Mamoswine. Some stages it was ideal not to use the DD because Disruptions started combos.
