pokemon rocket booster pack 1st Edition Team Sealed Mint Vintage WOTC 1999 Includes 10 vintage cards and 1 guaranteed holo 21.1 Gram “Heavy” First Edition

Assuming your opponent tries to stop it as soon as you lose a flip, with Krark's Thumb out you have a 17.80% chance to drain 31 life (13.35% chance to drain 62!), but unlike most of the other coin flip cards it's not all-or-nothing, you still drain for each previous flip you won

Dark Ritual also gets played in high powered combo decks like Storm, that try to play a barrage of spells on a single critical turn before casting Tendrils of Agony

Each small creature you play makes you a token, allowing you to go wider faster

This serpentine Pokmon slithers silently, ready to strike with its potent venom

Also 3 Pikachu promo cards are included, which includes a new Pikachu Holo card 124/S-P

Not sure how good it ends up being in practice however
