稜鏡陣列

Text:

聚輝～稜鏡陣列進戰場時上面有數個晶體指示物，其數量等同於施放稜鏡陣列時用來支付費用的魔法力顏色數量。從稜鏡陣列上移去一個晶體指示物：橫置目標生物。：占卜3。（檢視你牌庫頂的三張牌，然後將其中任意數量的牌以任意順序置於你牌庫底，其餘則以任意順序置於你牌庫頂。）

Rulings:

• 8/25/2015 The maximum number of colors of mana you can spend to cast a spell is five. Colorless is not a color. Note that the cost of a spell with converge may limit how many colors of mana you can spend.
• 8/25/2015 Unless a spell or ability allows you to, you can’t choose to pay more mana for a spell with a converge ability just to spend more colors of mana. Likewise, if a spell or ability reduces the amount of mana it costs you to cast a spell with converge, you can’t ignore that cost reduction in order to spend more colors of mana.
• 8/25/2015 If there are any alternative or additional costs to cast a spell with a converge ability, the mana spent to pay those costs will count. For example, if an effect makes sorcery spells cost <img src="/Handlers/Image.ashx?size=small&amp;name=1&amp;type=symbol" alt="1" align="absbottom" /> more to cast, you could pay <img src="/Handlers/Image.ashx?size=small&amp;name=W&amp;type=symbol" alt="White" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=U&amp;type=symbol" alt="Blue" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=B&amp;type=symbol" alt="Black" align="absbottom" /><img src="/Handlers/Image.ashx?size=small&amp;name=R&amp;type=symbol" alt="Red" align="absbottom" /> to cast Radiant Flames and deal 4 damage to each creature.
• 8/25/2015 If you cast a spell with converge without spending any mana to cast it (perhaps because an effect allowed you to cast it without paying its mana cost), then the number of colors spent to cast it will be zero.
• 8/25/2015 If a spell with a converge ability is copied, no mana was spent to cast the copy, so the number of colors of mana spent to cast the spell will be zero. The number of colors spent to cast the original spell is not copied.
