Metallener Koloss

Text:

Der Metallene Koloss kostet beim Wirken weniger, wobei X die Summe der umgewandelten Manakosten aller Nichtkreatur-Artefakte ist, die du kontrollierst.
Opfere zwei Artefakte: Bringe den Metallenen Koloss aus deinem Friedhof auf deine Hand zurück.

Rulings:

• 9/20/2016 If a permanent has <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its mana cost, X is considered to be 0.
• 9/20/2016 The total cost to cast Metalwork Colossus is locked in before you pay that cost. For example, if you control three noncreature artifacts each with converted mana cost 2, including one you can sacrifice to add <img src="/Handlers/Image.ashx?size=small&amp;name=C&amp;type=symbol" alt="Colorless" align="absbottom" /> to your mana pool, the total cost of Metalwork Colossus is <img src="/Handlers/Image.ashx?size=small&amp;name=5&amp;type=symbol" alt="5" align="absbottom" />. Then you can sacrifice the artifact when you activate mana abilities just before paying the cost.
• 9/20/2016 If the total converted mana cost of noncreature artifacts you control is 11 or greater, Metalwork Colossus costs <img src="/Handlers/Image.ashx?size=small&amp;name=0&amp;type=symbol" alt="0" align="absbottom" /> to cast.
• 9/20/2016 Once a player has announced that they are casting Metalwork Colossus, no player may take actions to try to change the number of artifacts its controller controls before that spell’s cost is locked in.
• 9/20/2016 Metalwork Colossus’s last ability can be activated only if it is in your graveyard.
