Katara, Seeking Revenge (TLE)

Legendary Creature — Human Warrior Ally

As an additional cost to cast this spell, you may waterbend {2}. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for {1}.) When Katara enters, draw a card, then discard a card unless her additional cost was paid. Katara gets +1/+1 for each Lesson card in your graveyard.

Reliable draw engine for Dimir control and self-mill strategies. Katara rewards you for filling your graveyard while offering flexible card selection—the waterbend cost lets you convert excess mana and creatures into pure card advantage, turning her into a repeatable value engine in Commander. Her power scales naturally in decks already running Lessons or self-mill payoffs, making her a solid mid-range threat that improves your mana efficiency and fills multiple roles at once.
