Muxus, Goblin Grandee 4RR
Legendary Creature- Goblin Noble
When Muxus, Goblin Grandee enters the battlefield, reveal the top six cards of your library. Put all Goblin creature cards with converted mana cost 5 or less from among them onto the battlefield and the rest on the bottom of your library in any order.
Whenever Muxus attacks, it gets +1/+1 until end of turn for each other Goblin you control.
The biggest downside is that if you cheat him into play it is likely because you already attacked with something that cheated him. There are going to be a lot of games where if this resolves you will win on the spot to.
Don't forget it can pull most changelings as well but thats probably of minimal importance.
