Myro, mastermind of the game

If Myro is your comander, he costs
{1}{c}{w}{u}{b}{r}{g} to play
Myro has all your commander's colors
Myro gains hexproof if he's blue,
haste if he's red,
+2/+1 and trample if he's green,
Vigilance if he's white and Lifelink if he's black
-This game's all mine
-you ain't beating my sliver deck
