'Friendly' Investment

You gain 1 life and your opponents lose 1 life for
every tapped permanent players control, and for
every treasure sacrificed this turn.

If you gain 5 or more life this way, draw 1 card and
untap up 2 permanents you control.

"...But remember, I don't make deals that don't
pay off... So, I hope you don't disappoint me."
