Prince Gumball (Hero Card)

Overview
Prince Gumball is basically the same as Lady Rainicorn but takes one less turn to activate use him if you'd like to heal as much as possible

Strategy
Use Prince Gumball with high defense creatures such as Diamond Dan or Embarrassing Bard so you can troll the opponent by healing one creature every 2 turns.

Counter
Strong creatures with high attack like Dr. Death and Steak Chop can easily send high defense creatures to the discard pile, or simply damage them and send them to the discard pile before Prince Gumball uses his ability, so you have 2-Turns
