Welle des Schreckens

Rulings:

• 6/1/2005 Will not generally kill zero cost creatures because the age counters go on before the ability triggers. If would be possible if something like Power Conduit were removing counters.
• 4/1/2008 This destroys creatures with converted mana cost exactly equal to the appropriate number, not equal to or less than that number.
• 4/1/2008 If you don’t pay the cumulative upkeep, you’ll sacrifice Wave of Terror before your draw step begins. It won’t destroy any creatures that turn.
