: Add . Activate only during an opponent's turn.
Lavinia rewards you for casting two spells a turn, churning out Clues for card advantage while her tap ability gives you two colorless mana on opponents' turns to fuel instants and counterspells. Play a tempo-control game: hold up interaction, cast a second spell to investigate, and grind opponents out with superior card flow before closing with a payoff or token swarm. Vigilance lets her attack and still leave mana up.
