Forum:Desteny hero dogma important question

When I read the card effect of "dogma" that it takes half of your opponent life points during opponent's stanbyphase it doesn't say anything that it only works once.

The tip page it says this: "Since this card halves the opponent's Life Points during their turn, it might be wise to simply leave it on the field without attacking. This will prevent it from running into Traps which might remove it from the field. In most situations, it will likely be able to wipe out whatever is left of the opponent's Life Points with a direct attack after its effect activates."

This tip sort of indicated that half your opponent's life points works more than once?96.44.92.186 (talk) 02:40, August 7, 2012 (UTC)
