Planar Chaos to Future Sight (Single Change View)

General changes

Old rule (Planar Chaos) New rule (Future Sight)

203.1b.

Some cards have no mana symbols where their mana cost would appear. This represents an unpayable cost. An ability can also have an unpayable cost if its cost is based on the mana cost of a spell with no mana cost. Attempting to play a spell or ability that has an unpayable cost is a legal action. However, attempting to pay an unpayable cost is an illegal action. If an unpayable cost is increased by an effect or an additional cost is imposed, the cost is still unpayable. If an alternative cost is applied to an unpayable cost, including an effect that allows you to play a spell without paying its mana cost, the alternative cost may be paid.
