I am playing this Route with an Early Erika fight. Forgot Blizzard is in 4th slot rather than 3rd slot as my muscle memory from Round 2 ruined my execution, so I died to Rival 5 because I Bite Venusaur instead of Blizzard. Amazing luck because I missed 2-3 Mega Kicks instead of 4-5 Mega Kicks on average. Overall I certainly see that there is some potential to do an Early Erika as it produces a much more consistent fight.
