painfully 20

Kicker (You may pay an additional as you cast this spell.) This spell can't be countered. Urza's Rage deals 3 damage to any target. If this spell was kicked, instead it deals 10 damage to that permanent or player and the damage can't be prevented.

Instant and sorcery spells you control have rebound. (Exile the spell as it resolves if you cast it from your hand. At the beginning of your next upkeep, you may cast that card from exile without paying its mana cost.)

If a red instant or sorcery spell you control would deal damage, it deals double that damage instead.
