Fafnir, the Corrupted

Fafnir, the Corrupt's power and toughness are
equal to the number of artefacts you control.
Whenever a non-token artefact is put into a
graveyard, create 1 colourless gold token,
then Fafnir, the Corrupt deals 2 damage to each
player.
You may cast up to 1 target artefact from your
graveyard each turn.
