Verazol, the Split Current

The copy 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.

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. Most notably, the copy is also kicked.

You can't remove more than two counters as Verazol's last ability resolves to copy the spell more than once. You can't remove just one counter from it if it has only one. If Verazol leaves the battlefield while its last ability is on the stack, you can't remove two +1/+1 counters from it at all.

If another creature enters the battlefield as a copy of Verazol, consider how much mana was spent to cast that creature to determine how many +1/+1 counters it enters with.

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. This doesn't apply to copying a permanent spell with a modal enters-the-battlefield ability.

The copy is created on the stack, so it's not "cast." Abilities that trigger when a player casts a spell won't trigger.
