Infernos power has to become exactly 20 for the trigger to happen, so if an opponent foolishly stacks a bunch of firebreathing triggers and you have a pump spell in hand, you can wait until Inferno hits around 18-19 power, pump it to 20 or above, and make it miss the damage altogether
10 Breath Of The Sleepless A little bit on the higher end for an enchantment but Breath of the Sleepless is a powerful one regardless
My suggestion is that you recude the draw to 2 cards, AND select a more restricted gamma of monsters that can be used with it
Good luck with your climbs
With a price like that, its no wonder that this card is considered the rarest and most expensive Pikachu card in history
This is a smart move, as the roster of cards is not big enough to reinvent the wheel for each Ink color combination, but one of them got a mechanic that eerily resembles a controversial one from Magic: The Gathering
