one piece card game kaido OP04-044 :: Super Rare TCG deck and set it as active Kaido ST09-004 - One Piece

Luckily, Mercenary Informer is a card that does exist, and it hits any Mercenary regardless of converted mana cost...including itself, but there's no need to waste activations on that (unlike Ghosthelm Courier, it doesn't tap)

While its valuable to recognize these edge cases, sticking to 60 cards is typically the optimal choice in Standard and other Constructed formats

Remarkably, there are multiple sales at this price, proving its not just a one-off

Choose a legendary creature and get ready to face off against multiple opponents at once

Although I think those who aren't familiar with Sanderson's work may roll their eyes, cosmere actually makes a lot of sense as a crossover and avoids common issues with the idea
