Salvar Drest, Arachnomancer

When a nontoken spider enters the battlefield under your control, put a 1/2 green Spider creature token with reach onto the battlefield.
Delerium - Spiders you control enter the battlefield with a +1/+1 counter on them as long as there are four or more card types among cards
in your graveyard.
Kessig's swarm weaves with a new purpose.
