Arthur, Marigold Knight

Mana cost: {2}{U}{R}{W}

Legendary Creature — Mouse Knight

Haste Whenever Arthur and at least one other creature attack, look at the top six cards of your library. You may put a creature card from among them onto the battlefield tapped and attacking. Put the rest on the bottom of your library in a random order. Return that creature to its owner's hand at end of combat.
