Goombish, The False King

When Goombish, The False King enters the battlefield, reveal the top six cards of your library.
Put all Goomba 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 Goombish attacks, it gets +1/+1 until
end of turn for each other Goomba you control.
