I have been able to surpass the 13th round when teaming up with Hilda for multi-battles in the Battle Subway. I've been using EV trained Tyranitar to set up a sandstorm for my Excadrill, but the opponent's Drilbur keeps killing our Pokemon with quick claw and earthquake.
Has there been a pokemon combination that has worked for you? Also, should I set Hilda to either attack, defend or balanced?
Many thanks.
….since you posted this a few days ago and nobodies replied…..maybe I suggest trying youtube for the particular battles and picking some hints from there? I'd love to help you but I haven't played pokemon in ages…..
