Fury of Urabrask

Compleation 1 (As long as you control a Mountain, you may remove a poison counter from
an opponent rather than pay this spell's mana cost.)

If no mana was spent to cast this, the next spell
with a single target you cast this turn can't be countered. Otherwise the next spell with a single target you cast this turn has storm.

All they need is a whisper of the Glorious Word.
