Petyr Baelish, Littlefinger

If you would create 1 or more treasures, you may create twice that many treasures instead. If you
do, you then lose life equal to the number of artifacts you control.
Sacrifice X treasures; take control of target
creature with converted mana cost X or less. You maintain control of that creature for as long as
you control X or more artifacts.
I did warn you not to trust me, you know.
