Liliana, Mortal Coil's End

You cannot control any Planeswalkers except Liliana and you may control more than 1 Liliana Planeswalker.
Swamps you control have "{t}: Target creature gets +1/+1 until end of turn."
If an Ally would be removed from the game, create a token copy of each creature in that player's graveyard except they are Black Zombies in addition to their other types.
