Multiple players must join together to challenge one player who takes on the role of an ultra-powerful raid boss. Should the raiding party conquer Magtheridon, the heroes win the chance to crack open the enclosed treasure pack and reap rewards not found anywhere else! Each raid deck contains 121 cards: 110 x Raid Deck cards, 10 x Exclusive card treasure pack, and 1 x Oversized Hero card.

The Magtheridon's Lair Raid Deck Display contains 6 identical Magtheridon's Lair Raid Decks.
