The Wishmaster

Indestructible, Trample
The Wishmaster's power and toughness are equal
to the number of cards in all players hands.
When a player would draw their first card each of
their turns, they may instead draw 3 cards.
At the beginning of each player's endstep, that
player loses life equal to the number of cards in
their hand.
When The Wishmaster deals damage to a player,
each player draws a card.
