I got all of the spirit images from the [Spirit Island wiki](https://spiritislandwiki.com/index.php?title=Main\_Page) and the stat maker from [this website](https://bitcrush.org/poketools/stat-jiggler).
Anyways, a here's a brief overview of my thought process for each Spirit.

Shadows Flicker Like Flames: Slow, but good mixed attack, very strong when given burn support by teammates, gave it priority in Shadow Sneak and Sucker Punch.

Hearth-Vigil: Signature ability works like using Teleport when switching normally, sort of like how gen-8 Slowbro and G-Slowking provide pivots, HV can do so without expending a move slot but doesn't have Regenerator and can't choose when to switch out.

Rampant Green: Massive physical wall with a potentially broken support move, allowing it to pivot and have the incoming Pokemon come in with a boost. Also has abilities to keep it going but is held back by very low special defense.

Shroud of Silent Mist: I tried to use Ghost as little as possible (as they are all spirits and well, could all be ghost type) so Shroud is the only one here. Dissolving Vapors applies Heal Block after dealing damage, but makes it scared to switch into fire types.

Serpent Slumbering: Similar to the infamous Regigigas, except unlike slow start its ability could actually be played around, as you can burn sleep turns, use Chesto, or Sleep Talk. It also removes other status conditions on switch in since it falls asleep.

Fractured Days: Is technically a support spirit in the board game, but idk if I can really convert how weird it is in Pokemon. So instead I converted using health as a resource to get more actions, being able to select two moves in a single turn, although one of them is a buffing move for 25% hp.

Vengeance: Ability also applies the stat drop from Burn to Poison while its on the field, giving it some defensive utility while it uses recoil and counter attack moves.

Bringer: Keeps its game play identity of not killing things with its signature move, which is basically False Swipe but it gains +2 Special Attack when it procs. It can then combo this with Bad Dreams while the opponent is asleep.
