Kalánika, Seraph Of Freezing

Flying, vigilance

Instant Frostbind — Whenever Kalánika or another Angel creature you control becomes blocked by a creature that doesn't share a creature type with it, prevent all damage that would be dealt to it until the end of your next turn.
If the blocking creature shares a creature type with it, damage is dealt as normal.

Shields of Frost Energy — Whenever Kalánika attacks and becomes blocked by a creature, counter the next spell your opponent casts.
