Yawgmoth, Lord of Wastes

At the beginning of your second main phase, if Yawgmoth, Lord of Wastes has one or more
loyalty counters on it, you may have it become a planeswalker until end of turn with "Yawgmoth,
Lord of Wastes can use the activated abilities
of all planeswalkers in the graveyard." It's still a creature.
Whenever a planeswalker dies, put a loyalty
counter of Yawgmoth, Lord of Wastes.
