dark explorers booster box B&W Blister Black & White: Dark Explorers

Larger deck boxes are great for holding cubes

I would round out the broken list with Sol Ring, Library of Alexandria, Mana Vault, Mana Crypt, and Ancestral Recall

Sometimes they are large enough to accommodate both players

add 1 monster with 2400 ATK/1000 DEF and the same Attribute from your Deck or GY to your hand, then, immediately after this effect resolves, you can Normal Summon 1 Zaborg the Thunder Monarch, Mobius the Frost Monarch, Thestalos the Firestorm Monarch, Granmarg the Rock Monarch, Raiza the Storm Monarch, or Caius the Shadow Monarch

Anytime any creature dies, yours or your opponents, you get to drain two life from an opponent and heal yourself two, putting some heavy pressure on your opponents
