Having judged at GenCon So. Cal. and last weekend the regional in Des Moines, IA I can certainly see that there are a great many that will have to become much better versed in the TIMING of certain effects. Keep in mind that Divine Wrath must be activated in response to the ACTIVATION of a monster's effect. Note that the activation doesn't necessarily coincide with when you decide to use the effect. As well, it would be a good move to study up on just what monster effects are continuous, there are a number of monster effects you might not consider continuous that are indeed deemed so by Konami.
On that note, look for cards in future sets to rely on such technical information. If you want to keep the edge in this game I highly recommend doing your homework. I plan to write an article or a long post on this topic soon.
