Darth Sion, Lord of Pain

When Darth Sion is removed from play by any
means, you may regenerate him during your next upkeep if you control another Sith creature. He becomes an X/X Zombie Sith, Where X equals 5
minus the number of regenerations, and gains
menace. He can not be regenerated to have below
zero power and toughness.
Darth Sion can not be blocked by creatures with greater power and can not have hexproof or indestructible.
