Muxus, Goblin Grandee

When Muxus, Goblin Grandee 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.
