Red Marker

Man Made Marker - {2}{r}, {t}: Put an Influence counter on target creature you control.

But Still Just As Scary - At the beginning of
your upkeep, exile the top X cards of target opponents library where X is the number of Influence counters on creatures you control. Until end of turn, you may cast spells from among those cards, and mana of any type can
be spent to cast those spells.
