Seath, The Scaleless

When Seath, the Scaleless enters the battlefield,
create an artifact token called Primordial Crystal.
Seath has Hexproof and Indestructible as long as
there is an artifact token called Primordial
Crystal on the battlefield under your control.
When Seath attacks, put a -1/-1 counter on each creature your opponents control without flying.
For each creature that dies this way, scry 1 and
draw a card.
