Tolarian Academy (330) [Urza's Saga] Mosaic Rare You may discard any numberRarity: R #: 330 Card Type: Legendary Land Description: T: Add U to your mana pool for each artifact you control. Flavor: The academy worked with timeuntil time ran out. TCGplayer Tip: Given the number of zero cost artifacts in Magic, it's trivial to build a deck that lets you tap Tolarian Academy for three or more mana on turn one. So it's no surprise that this card is banned or restricted in so many formats.
