One ruling from Wizards of the Coast
- 8 April 2016If multiple land cards are put into your graveyard at once, Crawling Sensation's last ability triggers only once. This could happen because an effect (such as that of Crawling Sensation's first ability) put them there from your library at once, or because they were destroyed at the same time (such as two land creatures that were dealt lethal combat damage).
