2009-02-01 Forestcycling is a form of cycling. Any ability that triggers on a card being cycled also triggers on Forestcycling this card. Any ability that stops a cycling ability from being activated also stops Forestcycling from being activated.
2009-02-01 Forestcycling is an activated ability. Effects that interact with activated abilities (such as Stifle or Rings of Brighthearth) will interact with Forestcycling. Effects that interact with spells (such as Remove Soul or Faerie Tauntings) will not.
2009-02-01 Unlike the normal cycling ability, Forestcycling doesn't allow you to draw a card. Instead, it lets you search your library for a Forest card. After you find a Forest card in your library, you reveal it, put it into your hand, then shuffle your library.
2009-02-01 You can choose to find any card with the Forest land type, including nonbasic lands. You can also choose not to find a card, even if there is a Forest card in your library.

Card is in preconstructed decks:
