Prototype X-8

Prototype X-8 is a Legendary Artifact Creature — Robot Octopus card from the Magic: The Gathering trading card game.

Its ability reads: "This spell costs {1} less to cast for each creature card in your graveyard. Whenever another creature you control enters, if you cast it, sacrifice it. Conjure a duplicate of it onto the battlefield. The duplicate perpetually becomes a Robot artifact in addition to its other types."

Prototype X-8 has a mana cost of {6}{U}{B}, which equals 8.0 total mana (converted mana cost/mana value).

It requires B, U mana to cast.

Mana cost is the amount and type of mana required to cast a spell in Magic: The Gathering.

Prototype X-8's mana cost of {6}{U}{B} means you need to pay that much mana from your lands or other sources.

Colored symbols (W=White, U=Blue, B=Black, R=Red, G=Green) must be paid with that specific color, while numbers can be paid with any color.

Converted mana cost (now officially called "mana value") is the total amount of mana in a card's mana cost, regardless of color.

Prototype X-8 has a mana value of 8.0. This is important for effects that care about a spell's total cost, like cascade or cards that say "mana value 3 or less."

Oracle text is the official, current rules text for a Magic card as maintained by Wizards of the Coast. It supersedes any printed text on older cards.

Prototype X-8's current oracle text is: "This spell costs {1} less to cast for each creature card in your graveyard. Whenever another creature you control enters, if you cast it, sacrifice it. Conjure a duplicate of it onto the battlefield. The duplicate perpetually becomes a Robot artifact in addition to its other types."
