Like Pelakka Wurm, Artisan of Kozilek is a huge beatstick with built-in card advantage. While the colorless mana-cost is nice, Artisan does take a little longer to cast than other large threats, but with some mana acceleration, 9 mana is highly attainable in multiplayer. The ability to bring back another huge creature or another tempo-swinging creature in addition to Artisan's huge body can really seal the deal on a game you are already winning or help you come from behind in a game you aren't. Then if Artisan can start attacking, it can hammer away at your opponent's mana base with its annihilator ability.
In many ways, Artisan feels like a multiplayer, timmy-centric eternal witness. Being mono-colored and providing such a huge effect at uncommon (so you can get them for less than a quarter), he fits in so many multiplayer decks and is hard to play against. I'm gonna go out on a limb and say that this is probably the best uncommon creature for multiplayer ever printed. I'm also gonna go out on a 2nd limb and nickname this guy "Bob Ross." Because he is an Artisan, get it?!?
