Taigam, Ojutai Master

Instant, sorcery, and Dragon spells you
control can't be countered by spells
or abilities.
Whenever you cast an instant or sorcery spell
from your hand, if Taigam, Ojutai 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.)
