Artful Acquisitor

Ascend (If you control ten or more permanents, you
get the city's blessing for the rest of the game.)
When Artful Acquisitor enters the battlefield,
you may gain control of target token.
At the beginning of your end step, if you control
fewer than ten permanents, create a Treasure
token. If you have the city's blessing, you may
instead create a token that's a copy of target
token you control.
