The pain master

Eminence: Whenever you cast a spell if the pain master is
in your commander zone or on the battefield whenever
you cast a spell you lose 2 life and discard a card
Whenever you discard a card , draw two cards
Whenever you lose life you gain doble that number
At your end step if you have more cards than
your starting hand
or more life than your starting life you lose
the game.
