How does this interact with Blasphemous act or similar high-damage boardwipes? Would I get to shoot someone for 13 damage for each sliver I have, or would it be capped to the sliver's toughness?
You get to deal 13 for each sliver. The damage that creatures can receive is not capped at their toughness.
Does this effect stack? Either way, seems like there's a janky combo deck with either blasphemous act, or even a damage doubler like furnace of rath or dictate of the twin gods. Bolt a sliver, pass the bolt along, then 24 to target player.
How would you "pass the bolt"? This only redirects to players and planeswalkers.
