When you Warp a card (including Cloudsnake Matriarch), draw a card.
Card sounds may differ from in-game as they get updated.
Flying - Flying units can only be blocked by other flying units, but can block ground units normally. They can also be directly attacked by Killer units and Relic Weapons.
Warp - You can see cards with Warp when they are on top of your deck, and you can play them as if they were in your hand.
