Sup /vp/.

I want to make a Hawlucha. What ability for it would be the best?

I can see valid strategies for all of them.

Limber: The Pokémon cannot be under the PARALYZE condition while having this ability.
Unburden: Speed is doubled once the held item is consumed.
Mold Breaker: The Pokémon's moves are not affected by foe’s abilities during battle

I feel Unburden might be his best ability combined with a berry but Mold Breaker could be extremely useful as well. What are you all doing?
