Vestera, Saint of Splendor

Whenever another Lost creature enters the battlefield under your control, each player exiles
the top card of their library.
Gods and Saints you control get +1/+3 and have
vigilance and reach.
"Vestera is popular with children; she is especially
gentle, and allows them to ride on her back or head as
she flies, showing them the world as they've never
seen it before." - Judiel
