Canoptek Spyder

Kicker {3} (You may pay an additional {3}
as you cast this spell.)
If Canoptek Spyder was kicked, it enters the
battlefield with three +1/+1 counters on it.
Whenever one or more +1/+1 counters are put
on a creature you control, if Canoptek Spyder
is in your graveyard, you may put
Canoptek Spyder on top of your library.
