Kicker {8}{R} (You may pay an additional {8}{R} as you cast this spell.)Urza's Rage can't be countered by spells or abilities.Urza's Rage deals 3 damage to target creature or player. If Urza's Rage was kicked, instead it deals 10 damage to that creature or player and the damage can't be prevented.

A spell or ability that counters spells can still target Urza's Rage. When that spell or ability resolves, Urza's Rage won't be countered, but any additional effects of that spell or ability will still happen.

If the target for Urza's Rage becomes an illegal target, the spell won't resolve and will be put into its owner's graveyard with no effect. This is true even if its damage can't be prevented and even though it can't be countered.

If a card or token enters as a copy of a permanent, the new permanent isn't kicked, even if the original was.

If a spell's kicker cost was paid, the spell is "kicked."

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.

If you put a permanent with a kicker ability onto the battlefield without casting it, you can't kick it.

The kicker ability doesn't let you pay a kicker cost more than once.

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.
