Rulings:

• 7/1/2013 Alternative costs, additional costs, cost increases, and cost reductions don’t affect a spell’s converted mana cost.
• 7/1/2013 If the target spell has <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in its mana cost, include the value chosen for that X when determining the value of the <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /> in Spell Blast’s mana cost. For example, if you wish to counter Volcanic Geyser (a spell with mana cost <img src="/Handlers/Image.ashx?size=small&amp;name=X&amp;type=symbol" alt="Variable Colorless" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" />) whose X is 7, you’ll need to choose 9 for Spell Blast’s X and pay <img src="/Handlers/Image.ashx?size=small&amp;name=9&amp;type=symbol" alt="9" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=U&amp;type=symbol" alt="Blue" align="absbottom" />.
