Ward Sliver
Creature — Sliver
As this creature enters, choose a color.
All Slivers have protection from the chosen color.
The first wave of slivers perished from the Riptide wizards' magic. The second wave shrugged off their spells like water.

The List (PLST)
• #LGN-25Rulings
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.
