binding of isaac chaos card Chaos Card + Mother

Finally, there's True Exodia

Sidenote - I love how everyone tried to play "Mulligan Mewtwo" using 4 of this and 56 psychic energy and Barrier their way to a win when a single Energy Removal card destroyed the strategy

If you're short of any of the above cards in any deck build shown and need a solid substitution, I recommend Jynx, whose attack does an extra 30 damage for every energy the enemy Pokemon has on them (making it great for hurting powerful Pokemon)

Maybe Standard Nature's Rhythm decks fetch their Craterhoof

Honestly, after seeing so many of them on this list, it was quite a relief that there isnt a Pikachu in the number one spot
