Elvish Hydromancer

If you copy a kicked spell on the stack, the copy is also kicked. If the copied spell is a permanent spell, the token the copy of that spell becomes when it enters is also kicked.

To determine a spell's total cost, start with the mana cost (or an alternative cost if another card's effect allows you to pay one instead), add any cost increases (such as kicker), then apply any cost reductions. The spell's mana value remains unchanged, no matter what the total cost to cast it was.

If it was kicked, Elvish Hydromancer's ability can target any creature you control, including itself. If it targets itself, the token that is created won't have been kicked, so the ability will not trigger again.
