That depends upon the rest of your Team.
If you have some more Defensive Pokemon, then go right ahead with Close Combat.
However, I'd suggest both Brick Break and Close Combat, if you haven't decided the other moves. Pros of
Close Combat :
Cons:
- Low PP
-Defenses Loss
Brick Break
- Decent Power
- More PP
- No negative Side-effects.
Cons:
- Lesser Power than Close Combat( about 45 Base Power difference)
So, it's actually up to you. If you don't get a good move, then go ahead with both.
