Tier 4 solo guides
Yes, they're possible, but the only viable one is Absol, which ranges from a 32% win rate (snarl/megahorn) to less than 10% (psycho cut/thunder). Ttar is technically possible, but requires different strategies depending on its moveset (iron tail/crunch is the most likely one to win against, but still is less than 1% winrate)
Would like to see an Absol solo guide for the real hardcore players and a Ttar solo guide for posterity.
