Invocation of Frost

Invocation of Frost is a common shaman spell card, from the Descent of Dragons set.

Strategy
The card is essentially a more expensive Glacial Shard with Rush, thanks to the Windswept Elemental generated by the Invoke effect. This makes Invocation of Frost perfect for locking down a dangerous enemy while trading into a smaller one.

You can combine this card with Electra Stormsurge or Zentimo to double or triple the number of times you Invoke.
