The Shadow Eel

Deathtouch (Any amount of damage this
deals to a creature is enough to destroy it.)
Whenever another creature dies, each opponent
loses 1 life.
{2}{b/g}{b/g}: Shadow Eel gets +X/+X, where X is the
total number of cards in your graveyard until
end of turn.
Locals try to warn everyone about how haunted
the lake is...
