Edgewalker

Text:

Cleric spells you cast cost less to cast. This effect reduces only the amount of colored mana you pay. (For example, if you cast a Cleric spell with mana cost , it costs to cast.)

Rulings:

• 10/4/2004 If you have more than one of these on the battlefield, the cost reduction is cumulative.
• 8/1/2008 You apply cost reduction effects after other cost modifiers, so it can reduce additional costs or alternative costs if they include <img src="/Handlers/Image.ashx?size=small&amp;name=W&amp;type=symbol" alt="White" align="absbottom" /> and/or <img src="/Handlers/Image.ashx?size=small&amp;name=B&amp;type=symbol" alt="Black" align="absbottom" />.
• 8/1/2008 If a spell has hybrid mana symbols in its mana cost, you choose which half you will be paying before determining the total cost. If you choose to pay such a cost with <img src="/Handlers/Image.ashx?size=small&amp;name=W&amp;type=symbol" alt="White" align="absbottom" /> or <img src="/Handlers/Image.ashx?size=small&amp;name=B&amp;type=symbol" alt="Black" align="absbottom" />, Edgewalker can reduce that part of the cost.
