Merek Puppetmaster

You may choose not to untap Merek during your
untap step.
Morbid - At the beginning of each end step, if a
creature died this turn, you get an experience
counter.
{t}: Exile target creature card with mana value X or
less from a graveyard, where X is the number of
experience counters you have, then create a token
that's a copy of the exiled card. When Merek leaves
the battlefield or becomes untapped, sacrifice that
token.
