I've found 3 different methods of wind bursting.
The first, if you want to attack, requires that you somehow get your speed down to 0, so good luck getting a 600 lb weight from the item mall. For this one do:
~shield smash
~cord
~speed up pet (or some say coma or unload wall, and some give different orders of assist, it really doesn't matter the order since they all miss, so long as you buff/debuff)
~ atk, atk with strongest attack

Next two options are to just assist.
First is if there's a water assist on the team.
If you can get slower than the water, then just assist in whatever order you find best, just use as many different spells as you can.
If you're faster than the water, us speed up on pet first then assist (careful on the last turn, since you're faster than the water, use speed up again, or maybe even shield smash if you're greedy XD)

The last one is the daring idea of replacing water with a wind (preferably a mage) O.O
for this one use shield smash when water would use GS since the purpose of both is to decrease the monster's defense for higher damage. for this one try
~shield smash
~speed up
~cord
~coma/shield smash
~shield smash

Let me know how those work ^^ and good luck
