Spectacular Skywhale

Creature — Elemental Whale

Flying Opus — Whenever you cast an instant or sorcery spell, this creature gets +3/+0 until end of turn. If five or more mana was spent to cast that spell, put three +1/+1 counters on this creature instead.

Rootha was humbled in the whale's presence. It was glorious and beautiful, all on its own terms.
