The Company

The Company can be your commander.
The Company enters the battlefield with an age counter on it.
Indestructible. Cumulative Upkeep: Sacrifice an Artifact.
At the beginning of your end step, you may
search your library for a permanent with a
converted mana cost of X or less, reveal it,
and put it into your hand, where X is the
number of age counters on The Company.
Then shuffle your library.
