Scales of Pitiless Justice

Indestructible, Shroud
Mana Burn (When a phase ends, any unused
mana left in a player's mana pool is lost. That
player loses 1 life for each mana lost this way.)
If a player would draw a card, except their first
card each draw step, that player must pay 2 life
or discard that card.
If a player would cast a spell without paying its
mana cost, that player loses life equal to that
spell's converted mana cost.
