Shi'Ren, Master of Strings

Manipulate (Your creatures can help pay for
this creature's {t} ability cost. Each creature you
tap pays for {1} or one mana of that creature's color.)
{5}{w}{b}, {t}: Destroy target permanent. Then, put
a number of 1/1 white Puppet creature tokens
onto the battlefield equal to that permanent's
converted mana cost.

A simple trade, really: Your soul for many.
