Neo Pinger Deck

I set out to build a pinger deck without a single pinger in it. Horshoe Crab is what started me on this idea. Use deathpits with a pinging soul collector to gain control of an enemies creature. The Sol ring is in the deck for the movement of the viridian longbow. Hypnotic specter never specifies combat damage in the card or oracle text. So if you can get an opponent down to no hand, you can ping them at the end of their draw step and they never get another card. Sideboard or main deck ideas would be apreciated. The lands in the sidebaord are just to post the deck
