Joker, Phantom Thief

Has Shroud if you control no treasures
When Joker is not blocked you may have him do no combat damage
if you do the defending player reveals the top card of their library until
they revel a creature than the defending player chooses 1
Join our cause-cast that creature without paying its mana cost
Item-look at the top 10 cards of your library, put one on top and the rest on the bottom
Gold-make x treasure tokens where X
is that spells Mana cost
