Well.....
Josu Vess is the biggest Lich
He's a big fat Lich
He's the biggest Lich in the whole wide world
He's a stupid Lich if there ever was a Lich
He's a Lich to all the boys and girls

On Monday he's a Lich
On Tuesday he's a Lich
On Wednsday through Saturday he's a Lich
Then on Sunday, just to be different,
He's a superkamayamayaliiiich

Have you ever met my friend Lillana's Bro?
He's the biggest Lich in the whole wide world

In all seriousness I was thinking that by himself, Josu is a pretty nice finisher. With kicker he is even more dangerous. The new shade allows you to get much devotion off one card and is a threat in himself for late game as its can power itself out with  Nykthos and isn't eating into the two drop spot like Nantuko Shade while being less frail. The rest is a decent control shell that you usually find in mono black devotion.
