"Alright, Flannery. Now that Odor Sleuth is in effect, let's make use of Reversal against a dark-type! The moment your HP is low enough, strike with that move!"
Flamethrower~Fire Fang~Flamethrower
IF Arcanine's HP is 20% or less, and Sableyee is not using a protective/evasive move, THEN use Reversal that turn instead.
IF Sableye uses a protective/evasive move, THEN use Howl that turn instead, and Fire Fang on all consecutive turns.
