Canoptek Spyder

When Canoptek Spyder enters the battlefield,
create three 3/3 black and green Scarab Swarms
artifact creature tokens with "discard a card,
sacrifice Scarab Swarms: destroy target creature
or artifact an opponent controls".
Whenever a Scarab Swarms token you own dies,
roll a D6. On a roll of 5+, return it to the
battlefield under your control.
