Sanvia's Appeal

Creatures you control have base power and toughness 1/1 and their activated abilities can't
be activated.
At the beginning of the end step, sacrifice
Sanvia's Appeal. If you do and you control at least one creature, draw three cards.
"When I found her, I pleaded for her life-giving wisdom. Instead she drew me close and silenced me
and the forest around us." - Amber, young druid
