pokemon sharpedo card ACE 9 - M EX - XY200a - Black Star Promo - [Water][Colorless][Colorless] Pokemon Sharpedo 37/132 Rare Secret

While mana intensive, the ability to repeatedly refute an opponent's turn by bouncing their guy combined with the ability to use Disappear as a way to "protect" your creatures in combat (cast Disappear on it and then attack freely, knowing you can save it from lethal damage) made for a very potent enchantment that acted more as a sorcery than an enchantment

You can tap any untapped creature you control to convoke a spell, even one you haven't controlled continuously since the beginning of your most recent turn

People also note that the quality control seems to be better for Japanese cards, so there are fewer mess-ups falling through the cracks, too

It's powerful, iconic, and a staple, making the fanciest versions of Dark Ritual highly valuable
