Havoc-seeker Medusa

Deathtouch to everything (Any amount of damage
this deals to anything is enough to destroy it. If this
deals damage to a player that player loses the game.)
When Havoc-seeker Medusa is put into the
graveyard from anywhere, exile it.
When Medusa enters the battlefield or attacks,
target creature loses all types, colors, and abilities
and has base power and toughness equal to its
converted mana cost.
