Hydreigon- Timid
Life Orb Full Sp Attack and Full Speed, (rest HP)

Dark Pulse
Dragon Pulse

Remember Dark Pulse is Egg move, I used a gen 4 Gyarados.

TimmahX posted a similar set, with Choice Band as item, which is my doubles item of choice for Hydreigon

My friend used this in the lead at the Subway, and won! Since then it has been my lead, and I am not sorry for it! A big thanks!

Since I voted for Hydreigon, I should post my set. Like I mentioned I give Dk Pulse Deino to kids who are having trouble with the elite four, then they raise it and win. A fine pokemon all around!
