Rhys Fintan, the Candle Smith

At the beginning of each upkeep, make a Candle
Token. (It's an artifact with "{t}, Sacrifice this
artifact: Deal 1 damage to any target.")
Sacrifice two Candles: Exile the top two cards
of your library. You may play them this turn.
{t}, Sacrifice Six Candles: Destroy all nonland permanents except Rhys Fintan, the Candle
Smith. It won't untap on your next uptap step.
