Gothrag, the Conqueror

Eminence — If Gothrag is in your command zone
or on the battlefield, if you have half your
starting life or less, creatures you control have
Haste.
Deathtouch, Indestructible
When Gothrag attacks, if the defending player's
life total is greater than or equal to their starting
life, he has Double strike and Trample.
When a player loses the game, put +1/+1
counters on Gothrag equal to the number of
cards they had in their final hand.
