Thone, the Inexorable

Cats you control have deathtouch, menace, and protection from white.
Whenever a Cat you control dies, you may pay 1
life. If you do, you get an experience counter.
At the beginning of each upkeep, if Thone, the Inexorable is on the battlefield or in your
graveyard, if you have 9 or more experience
counters, return target Cat creature card from
your graveyard to the battlefield.
