Reasons
This set bulks and bulk creeps many things. 68 Speed outspeeds uninvested Chartiki, if you need to Slap Down or Baffle on it. Rough Up is STAB, and can deal some extra damage against bugs such as Terraclaw, Odasho, and Propae. Gain Drain seems weird, but it can wipe out setup Loomians, but if those aren't a problem, then use Shadow Sprint for priority. Baffle is for lowering the opponent's speed for the Loomian you are going to switch to. Slap Down can remove opponents' items such as essences to make you bulkier or stronger against them.

Tank is the easier and better ability to get since it allows you to bulk lots of stuff.

Health Amulet is so you heal consistently, making it harder and more annoying to kill Ursnac.
