Magic The Gathering Cards of types 'Bird' and 'Snow'

Flying Rimefeather Owl's power and toughness are each equal to the number of snow permanents on the battlefield. {1}{S}: Put an ice counter on target permanent. Permanents with ice counters on them are snow.

Flying {S}, {T}: Draw a card, then discard a card. ({S} can be paid with one mana from a snow source.)

Flying {S}{S}: This creature gains shroud until end of turn. ({S} can be paid with one mana from a snow source. A creature with shroud can't be the target of spells or abilities.)

Flash Flying When this creature enters, if you control another snow permanent, exile target permanent other than this creature. Return that card to the battlefield under its owner's control at the beginning of the next end step.
