Ranni the Witch

When Ranni enters the battlefield, create
a 3/3 green legendary creature token named
Blaidd with "If any damage would be dealt to
Ranni the Witch, prevent it. Blaidd is dealt
that much damage."
Instant and Sorceries cost {1} less to cast.
Ranni has hexproof as long as you control
Blaidd.
