Lifeforce Candle

Limbo (You may exile this card face down from your hand for {2} & draw a card. Only return
this card when you lose life & pay {1}. Reveal the card before returning it to your hand)
Whenever you cast a spell from exile, you may pay {w/b}. If you do, each opponent loses 1 life &
you gain life equal to the total life lost this way.
Final Hour- If you have 10 or less Life, you may now apply this to all spells you cast.
