Serra's Sanctum [Urza's Saga] Fiend/Effect If any of those cardsRarity: R Card Type: Legendary Land Description: T: Add W to your mana pool for each enchantment you control. TCGplayer Tip: Much like Gaea's Cradle and Tolarian Academy, which are also from Urza's Saga, Serra's Sanctum taps for an absurd amount of mana in any deck built around it. It doesn't take many enchantmemts to break this card in half.
