Ous Egg

Defender, hexproof
Whenever an instant or sorcery spell you control
would be countered, sacrifice Ous Egg. Create a
2/2 blue Drake creature token with flying and
cipher that spell card onto the token. (Exile the
spell card encoded on the creature token. Whenever
that creature deals combat damage to a player, its controller may cast a copy of this card without paying
its mana cost.)
