Dimensional Route Scout

Flash, flying, ward 1
Split second (As long as this spell is on the stack,
players can't cast spells or activated abilities that
aren't mana abilities.)
When Dimensional Route Scout enters the
battlefield, exile each spell currently on the stack,
unless their controller pays {x} for each card exiled
this way, exile them with a 'G' counter on them.

Historic permanents gain "{t}: {c}or {e}, then exile
this permanent."
