op 8 booster box One Piece TCG: Two Legends Pack [OP-08] Those who rely on Japanese original products from the OP BANDAI HOBBY, One Piece TCG

Mausoleum Secrets Next up is Mausoleum Secrets, a 2-mana instant that allows you to search up a black card with a mana value equal to or greater than the number of creatures in your graveyard

6 Eternal Soul Eternal Soul is another continuous trap card, and it has a really powerful effect

The cost-reduction ability of Korvold, Gleeful Glutton doesn't change its mana cost or mana value, only the total cost you pay

Alternately, if you want a slightly more gradual on-ramp, the new planeswalker decks are a good place to start if you want to try out the game around the kitchen table

This was pretty unlikely anyway given how many potential finishers the deck has, but its worth noting regardless
