Reasons
Icicle Trap is a nice Hazard to set when you have extra time to do so. Gain Drain can slurp boosts out of Obsidrugons that are setting up on you. Bane of Haste can have a whole team based off of it, so that slow Loomians can crush the fast ones. Phantom Slash is spirit STAB, and Chilly Chomp is Ice STAB.

Parting gift is the only possible ability, and it's OK.

Health Amulet helps the bulk of Icigool, but Spirit and Ice Essence can boost the STAB moves if you already have a Loomian with a Health Amulet.
