Could I win?

Last tournament I went to I hurt my wrist by launching very hard and every time I launch now it hurts while granted I can do like 3-4 launches before it gets more and more painfully I have a tournament in the RC game store next week on Saturday my current combo is 

Golem Rock
7-70
rush

Phoenix Wing 
9-60
Point

shark edge
3-60
Flat

Could I win?
If you're experiencing wrist pain from launching i highly suggest you take a break for a week or so. Look up some carpal tunnel stretches. Repetitive stress injury is no joke, take it from me...

That being said, of your insist on still playing, overall that deck is fine, though might struggle into things like SilverWolf and CobaltDragoon.
Very much agree with fabelavalon after a tournament I always take a break if I'm in pain. Try not to push yourself. Dont wanna pull a Free De La Hoya haha.
