When you play a spell, Kenna gets +2/+2 and Flying this turn.
Tribute: Draw a spell from your void.
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.
Killer - A unit with Killer can make one special attack directly against an enemy unit. This can be done the turn it's played, and can target any unit, regardless of Flying, Aegis, or other special abilities.
Tribute - Cards with Tribute have an additional effect when played if a unit went to your void this turn. This includes units that die or units you discard from your hand and deck.
