2/3 man articuno

For reference, this team will do it with three trainers with or without weather- or friend boost.
A two-man seems impossible sbecause a near perfect Tyranitar will need 650 seconds. Divided onto two trainers you still won't have enough time.

Try pokébattler.

Seems like a three man could be easily possible, im already going out groups of four just to be safe.

looks like I really had to eat my words about smack down not being much use for a while
