Daven, the Wonderer

Mytic Aura - When a player cast a spell, pay 6 mana. If
the casting player roll the dice with a number smaller
than you, the the spell is disrupted.
Whenever Daven or another nontoken Spirit you control
dies or inflicts combat damage to a player, create
a 1/1 Spirit creature token with flying.
When ever Daven blocks, put a +1/+1 counter on each
Spirit creature you control.
