Muxus, Goblin Grandee

When Muxus enters, reveal the top six cards
of your library. Put all Goblin creature cards
with mana value 5 or less from among them
onto the battlefield and the rest on the bottom
of your library in a random order.

Whenever Muxus attacks, it gets +1/+1 until
end of turn for each other Goblin you control.
