Reliea City

Trample
When Reliea City enters the battlefield, it has 4 slumber counters. Once every turn, you may add or remove 2 slumber counters from Reliea City. As long as Reliea city has a slumber counter on it, it's a land. (It's not a creature.)
The fresh air, the marketplace, the noises-Wait, did that rock just move?
