Why it's great
In endless once you finish your carry phase (wave 2000-3000), you need to fuse a mold breaker mon to a sturdy mon (with ground, rock or steel typing) to become your support. This is detrimental to bypassing recovery tokens as it rocks heal block, soak (so that salt cure deals extra damage), gastro acid (f- you goldhengo) and explosion (pivot move)
