Seto Kaiba, Dragon Master

Instant, sorcery, and Dragon spells you control
can't be countered.
Whenever you cast an instant or sorcery spell
from your hand, if Seto Kaiba, Dragon Master attacked this turn, that spell gains rebound.
(Exile the spell as it resolves. At the beginning of
your next upkeep, you may cast that card from
exile without paying its mana cost.)
