Seaking – Water – HP90
Stage 1 – Evolves from Goldfish Cracker
[W] Wet Horn: 10+ damage. This attack does 80 more damage if this Pokemon was healed during this turn.
[C] Assault: 40 damage. This Pokemon does 10 damage to itself. Stop hitting yourself!
Weakness: Grass (x2)
I tested a deck using this, Rainbow Energy, Jynx, and Dugtrio (which I might post in deck garage). Dugtrio and Rainbow Energy put damage counters on Seaking for Jynx to heal and allow wet horn to do 90 for 1. Dugtrio can also serve as an attacker and if all else fails, there's assault (which can set up a wet horn next turn). It works surprisingly well for a deck with no pokemon above 90HP. But I'm wondering if there's any other ways to damage yourself and heal. So far, all I can think of are a few stadiums one that heals 30 from water and lighting and the magma which does 20 to all non magma).
