Career Opportunist

Haste
As long as an opponent controls an artifact,
Career Opportunist has "{t}: Create a Treasure
token. (It's an artifact with "Tap, Sacrifice this
artifact: Add one mana of any color.") Otherwise,
it has "{t}: Career Opportunist deals 1 damage
to target player."

"If you don't let me walk out of here with my gold,
there will be a price to pay."
