Armor Sliver

All Sliver creatures have "{2}: This creature gets +0/+1 until end of turn."

Tempest Remastered

Premium Deck Series: Slivers

Tempest

Each Sliver gains "o2: This creature gets +0/+1 until end of turn."

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.

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.
