I was making a Jirachi when suddenly, I saw Doom Desire in usually useless moves. Doom Desire has 140 attack power, 100 accuracy, and takes two turns to hit, which can be good depending on what kind of situation your in.
The reason why Doom Desire is bad is because it takes two turns to hit. This will be bad in many more situations than it could be good. It is very easy to counter; while it breaks through Protect, the opponent can just switch in to a Pokémon that resists Steel. There are actually many of these types, so the opponent is very likely to have a Pokémon that resists, or even quad-resists the move.
252 SpA Jirachi Doom Desire vs. 252 HP / 0 SpD Heatran: 45-53 (11.6 - 13.7%) -- possible 8HKO

You are better off using Iron Head or Flash Cannon. Iron Head is especially good because of Jirachi's access to Thunder Wave, and ability Serene Grace.
