digimon cards 1999 booster box Series 2 one Pack fresh from a sealed Digital Monsters Digimon Vintage Japanese Anime Pack

Many commonly used cards in the Pokemon TCG require a discard for cost, and card advantage is central to the gameplay

Dark Depths was a bulk rare for years until the printing of Vampire Hexmage made it a lot easier to get your 20/20 Marit Lage token

Trap Dustshoot can also be a good way to take care of Sinister Serpent, but this strategy is only recommended for aggressive decks

You can obtain the Tauros ex (4-Diamonds rarity) card by opening Mega Rising: Mega Altaria from Mega Rising set

However, as Rewind Watches are rarer to come by than even Wonder Hourglasses, I'd recommend saving this until there's a card you just can't live without
