Hello;
The move "Destiny Bond" don't wor at all.
Definition from "bulbapedia" :
Generations II to IV
When Destiny Bond is used, until the user moves again, if the user faints as the direct result of an attack the attacking Pokémon also faints. If the user takes another turn (including 'inactive' turns such as those spent sleeping or flinching), the effect disappears.
A Pokémon defeated by this move will faint before the Pokémon that used Destiny Bond.
Destiny Bond does not activate from indirect damage such as weather damage, damage from Leech Seed, and Future Sight. Destiny Bond also bypasses Focus Sash, Sturdy, and Magic Guard.
Destiny Bond has no effect if an ally causes the user to faint.
Generation V
A Pokémon defeated by this move will now faint after the Pokémon that used Destiny Bond, meaning that if Destiny Bond is used by the last Pokémon on a player's team, and the last Pokémon on the opposing team makes it faint, the opposing player will win.
Destiny Bond can affect non-adjacent foes.
Best Regards
