The archetype that Sliver Swarm focuses on entirely is Combat: the deck provides tons of cards that greatly increase its effectiveness in combat, from dishing out extra damage with Bonescythe Sliver to providing evasion with Cloudshredder Sliver to drawing card on combat with Synapse Sliver
A first take might look as such: Creatures (13) Planeswalkers (8) Lands (24) Spells (15) 7) Strangleroot Geist *sigh* If only this card werent green the ability to play a hasted two-power attacker for two that returns to play with a +1/+1 counter if its killed is incredibly powerful, but is limited in this case by the extent to which it fits into a shell that does something (i.e., isnt green)
You could get two free spells of this if very lucky, but you can always cast one of each to get the bonus
