Misty, the Psychopomp

At the end of your turn, create Streya, a legendary
0/1 Spirit Token with "Whenever a creature
other than Streya is targeted by an ability or spell
controlled by an opponent, you may choose
Streya as that spell's target. Exile Streya"
Whenever another Creature you control is destroyed, you may pay {2}. Create a creature
token, that is a copy of that creature.
It's a Ghost in addition to its other types.
