Katara, Seeking Revenge

Texto de reglas

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.
