Moritte's Vessel

Changeling (This card is every creature type.)
Trample
Moritte's Vessel enters the battlefield with four
frost counters on it. As long as Moritte's Vessel
has frost counters on it, it is not a creature and is
a vehicle with crew 6. When Moritte's Vessel
attacks you may remove a frost counter from it.
Moritte's Vessel has power and toughness equal
to the number of snow permanents you control.
