All Slivers have “: This permanent deals 1 damage to target attacking or blocking creature.”
"They have long kept us under attack, but we do not lack for ammunition. The very bodies of our foes arm us against them."
—Adom Capashen, Benalish hero
If the creature type of a Sliver changes so it’s no longer a Sliver, it will no longer be affected by its own ability. Its ability will continue to affect other Sliver creatures.

Abilities that Slivers grant, as well as power/toughness boosts, are cumulative. However, for some abilities, like flying, having more than one instance of the ability doesn’t provide any additional benefit.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
