Entomb: Each unit in your deck randomly gets Flying or Charge.
Card sounds may differ from in-game as they get updated.
Charge - Can attack the turn it is played.
Entomb - The ability of a unit with Entomb will activate when it dies. This combines well with effects that sacrifice units as a cost.
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.
