Kal, Herald of Second Chances

Flying, ward {2}

Instant, sorcery, and Human spells you control can't be countered.
Whenever you cast an instant or sorcery spell from your hand, if Kal, Herald of Second Chances 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.)

"I accept this journey."
