Garm, Evocation Archmage

Ward 10
When you cast your first spell each turn, copy it
for each opponent you have. You may choose
new targets for the copies.
Spells you cast have Cascade.
Whenever you counter a spell, Garm deals
damage to any target equal to the countered
spell's mana cost. Whenever you cast an instant,
counter target spell if its mana value is less than
or equal to the mana cost of your instant.
