All Slivers have “When this permanent enters, you may fateseal 1.” (To fateseal 1, its controller looks at the top card of an opponent’s library, then they may put that card on the bottom of that library.)
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.

This ability triggers when Mesmeric Sliver itself enters.
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.
