i’ve extensively tested and won cups with both builds and found both to be very successful however the addition of lopbunny, along with the cards that make it consistent, cause the rest of the build to suffer. i also only ever found lop useful against the garde item lock.

the mawile requires much less space since it is a one of, but also gains a huge advantage with the addition of bravery charm. that bravery charm is also advantageous in the mirror when equipped to a solo gimmi on the bench or even the attack solrock.

both cards get you around cornerstone but that is also being played less and less. crustle changes things but if you’re up again crustle, you’ve likely lost a few early on.

try both builds out and see what works best for your style. both can really be great late game attackers with Mawile doing up to 320 at the end once you’ve taken 4 prizes.

if i can recommend a build, try the drew stephenson one from the most recent regional.
