Constricting Sliver

Slivers in this set affect only Sliver creatures you control. They don’t grant bonuses to your opponents’ Slivers. This is the same way Slivers from the Magic 2014 core set worked, while Slivers in earlier sets granted bonuses to all Slivers.

If a creature token is exiled, it ceases to exist. It won’t be returned to the battlefield.

The exiled card will return even if the Sliver whose ability exiled it doesn’t have that ability at the time (perhaps because Constricting Sliver is no longer on the battlefield).

The Sliver that enters the battlefield is the source of the ability that exiles the creature. For example, if a blue Sliver enters the battlefield under your control, the ability can target and exile a creature with protection from white.

In a multiplayer game, if the Sliver’s owner leaves the game, the exiled card will return to the battlefield. Because the one-shot effect that returns the card isn’t an ability that goes on the stack, it won’t cease to exist along with the leaving player’s spells and abilities on the stack.

Abilities that Slivers grant, as well as power/toughness boosts, are cumulative. However, for some abilities, like indestructible and the ability granted by Belligerent Sliver, having more than one instance of the ability doesn’t provide any additional benefit.
