Irala, Princess of Pale Scales

Hexproof from instants and sorceries
Whenever a land enters the battlefield under an
opponent's control, if they control more lands
than you, that player may pay {2}. If they don't,
create a Treasure token and a 3/3 white Dragon
creature token with flying.
She carries the blood of the Pale's monarch, a raw
essence that which wards her flesh, and summons
winged armies.
