Giant of the Four Ways

As long as you control four or more creatures, creatures you control have indestructible. The same is true for artifacts, enchantments, and lands.
"The giants spoke to the people: '10 0 steps north,
10 0 steps south, 10 0 steps east, 10 0 steps west.
If you have need, call us in a loud voice.'"
--Tale of the Four Giants
