Team notes:
- Don't check opponent until first battle of Round 6 (always go Latios/Heracross unless you recognize trainer name as a Swimmer, etc.)
- Jolly Heracross is necessary to outspeed base 100 and 110s, including threatening ones like Espeon
- Thunder is a 94% range on opposing Zapdos, which become a threat to Latios without Ice Beam
- Tucker 2 always leads Swampert (53% HP Grass range); can die if you miss range into Mirror Coat or freeze (Meta should be 2nd)

Routing notes:
- You often see Water teams (Swimmers, Fishermen) and Rock teams (Ruin Maniac, Hiker), so having Pokemon that can OHKO most of them is important
- Choice Band is very good since you have information about entire teams
- Exploders are good
- Slaking seems too slow since it needs 3 turns to win
- Speed tiers are different because of 3 IVs

Ideas:
- Zapdos (Mild @ Lum Berry, TB/HP Grass/Drill Peck/Thunder)
- Metagross (Adamant, MM/EQ/SB/Explosion)
- Latios (Modest, Psychic/TB/IB/Surf)
- Heracross (Jolly @ Choice Band, Megahorn/Brick Break/Earthquake/HP Bug)
