 * Q2736: In to the "when placed" ability of "Man Dragon Shield, Philome", this card was discarded. The opponent decided to not drop a hand card and not look at the deck, and then casts "-The Arcane Crown​- Al Coronation" to search the entire deck for Item. Will they be limited to the top 4 cards?
 * A: Yes they will. If they choose to not apply the effect that look through the entire deck, neither will this effect apply, until the next time such effect is applied this turn. For this, since the effect of "Philome" was not applied, thus the deck was not looked at, this effect will keep applying, until the next time such effect applies
