Xagorit, the Spark Consumer

Haste, flying, protection from Planeswalkers
Whenever Xagorit attacks or blocks, exile target
Planeswalker until Xagorit leaves the battlefield.
Xagorith gets two +1/+1 counters for each Planeswalker exiled this way.
{4}{u/r}: Xagorit gains hexproof and indestructible
until end of turn. This ability costs X less to
