Competitively, my Spiritomb is a tank. Mixed wall, in fact. However, it's speed is garbage at very low 108. I wanna have fun with Destiny Bond on it's moveset, but obviously Spiritomb won't be outspeeding much to revenge kill with Destiny Bond.
Pay attention this scenario:
Gengar used Dazzling Gleam. (Spiritomb lives with 1 hp)
Spritomb used Destiny Bond.
Gengar used Dazzling Gleam.
Will Gengar faint because of Destiny Bond being the last move Spiritomb used? Correct me if I am incorrect.
