Sword of Wealth and Power

Equipped creature gets +2/+2 and has protection from instants and from sorceries.
Whenever equipped creature deals combat damage to a player, create a Treasure token. When you next cast an instant or sorcery spell this turn, copy that spell. You may choose new targets for the copy.

The Big Score

You can’t choose to pay any additional costs for the copy. However, effects based on any additional costs that were paid for the original spell are copied as though those same costs were paid for the copy too.

If the copied spell divides damage or distributes counters among a number of targets, the division and number of targets can’t be changed. If you choose new targets, you must choose the same number of targets.

If the spell that’s copied has an X whose value was determined as it was cast, the copy will have the same value of X.

If the spell that’s copied is modal (that is, it says “Choose one —” or the like), the copy will have the same mode or modes. You can’t choose different ones.

Protection from instants and from sorceries means that the equipped creature can’t be the target of instant spells, sorcery spells, or abilities from instant or sorcery cards (such as an ability of an instant card that triggers when that card is cycled), and all damage that an instant or sorcery spell or card would deal to it is prevented. Nothing other than these events is prevented or illegal.

The copy created by Sword of Wealth and Power’s delayed triggered ability will have the same targets as the spell it’s copying unless you choose new ones. You may change any number of the targets, including all of them or none of them. The new targets must be legal.

The copy made by Sword of Wealth and Power’s delayed triggered ability is created on the stack, so it’s not “cast.”
