הנה, נמצאה תשובה (מסתבר שRune ענה על שתי השאלות שהעלנו פה, איך עוצרים Cycling ואם זה עושה Trigger לAstral Slide):
From Saturday School #29 by Rune Horvik, Saturday, May 24, 2003:
Q: If someone cycles a Slice and Dice, what can I stop with Stifle? Is there any way to counter the cycling to prevent Astral Slide from triggering?
A: Stifle can counter either the cycling card draw (which is an activated ability) or the 1 damage to each creature triggered ability. Note that once the cycling cost has been paid, the two abilities are independent. To stop the damage, you'll have to counter the damage ability; to stop the player drawing a card, you'll have to counter the cycling. One Stifle can't stop both.
As for Astral Slide, its triggered ability works just like Slice and Dice's. Cycling a card will immediately trigger Astral Slide - countering the cycling won't do anything to Astral Slide's triggered ability. You can counter the triggered ability of the Slide, though, to prevent the creature from being removed from the game.
מה שכן, צדקת בזה שזה יעצור רק את האפקט שליפה או את האפקט הנוסף. אני פשוט לא אמרתי שזה עושה את שניהם,
. אני יכול לעשות Stifle על Cycling של Lay Waste!
