Chazaan Druid

Atemporal (Unless it is the target of a spell or
an ability, this creature is treated as though it
doesn't exist by spells and abilities.)
{t}: Add {g} or {u}. If this mana is spent to
cast a spell with atemporal or phasing, that spell can't be countered.
Wrapped in the echoes of time, the Isles of Chaza became present vestiges of a distant past.
