The Seven Sins

This spell can't be countered.
Unforgiveable—At the beginning of each players endstep, that player loses a life for each damage
that was dealt this turn.
Whenever a creature attacks, that creature's controller flips a coin. If heads, The Seven Sins
deals 4 damage to any target of that player's
choice. If tails, that player gains 3 life and
discards a card.
