Brood Sliver
Premium Deck Series: Slivers — rare
Creature — Sliver
Brood Sliver rulings:
2013-07-01: 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.
2013-07-01: 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.
2004-10-04: This card’s controller controls the triggered ability, but the controller of the Sliver that deals damage to a player decides whether or not to put the token onto the battlefield under their control.
