Yu-Gi-Oh! Power Of Chaos: Joey The Passion Cheats

While the Trap Card "Magic Thorn" is active
on the field, when your opponent discards any number of cards
from the deck (for example, Needle Worm, Gravekeeper's Servant)
it does not count as damage to Life Points, and the card just
says discard. The card was supposed to activate even if your opponent
discards from its deck.
