Whenever an opponent casts a spell, counter that spell and put a depletion counter on Decree of Silence. If there are three or more depletion counters on Decree of Silence, sacrifice it.
Cycling 4UU (4UU, Discard this card: Draw a card.)
When you cycle Decree of Silence, you may counter target spell.
10/1/2008 Cycling is an activated ability. Effects that interact with activated abilities (such as Stifle or Rings of Brighthearth) will interact with cycling. Effects that interact with spells (such as Remove Soul or Faerie Tauntings) will not.
10/1/2008 When you cycle this card, first the cycling ability goes on the stack, then the triggered ability goes on the stack on top of it. The triggered ability will resolve before you draw a card from the cycling ability.
10/1/2008 The cycling ability and the triggered ability are separate. If the triggered ability doesn’t resolve (due to being countered with Stifle, for example, or if all its targets have become illegal), the cycling ability will still resolve and you’ll draw a card.
10/1/2008 You can cycle this card even if there are no targets for the triggered ability. That’s because the cycling ability itself has no targets.
