Removing three damage from a character is an enormous asset and can help keep the strongest cards in play, and drawing cards for each point healed sweetens the deal to an absurd degree
New cards, like the coveted Treasure Rare and the Special Rares, are just as sought-after as the manga rare
For example, if you have six cards in hand as Doctor Octopus's last ability resolves, and you also control Thought Reflection (an enchantment that says "If you would draw a card, draw two cards instead"), you'll end up drawing four cards
I would like to try this with a few more ETB/die effects
Block icon 2 Effect [Counter] If you have 2 or less Life cards, up to 1 of your Leader or Character cards gains +3000 power during this battle
This would be exceptionally strong in a Pirate-themed deck or using Captain Hook cards from any of the Lorcana Chapters
