Light a Candle

Create a 2/1 red candle creature with "If this
creature would die, and it's your turn, put a -1/-0
counter on it instead. If its power is 0, exile it.
Once per turn, you may discard a card. If you do,
put a +1/+0 counter on all candles you control."
When Light a Candle is put into a graveyard
from anywhere, shuffle it into its owner's library.
