You can, however, pay additional costs, such as kicker costs. If the card has any mandatory additional costs, you must pay those. — If you don't have an enchantment, instant, or sorcery card in your hand, you won't be able to pay Saruman of Many Colors's ward cost. — If you don't want to cast the copy, you can choose not to; the copy ceases to exist the next time state-based actions are checked. — You cast the copy while the ability is resolving and still on the stack. You can't wait to cast it later in the turn. — You don't choose a target for Saruman of Many Colors's ability at the time it triggers.
