Forum:Blackwing shura and armor master rulings nid help

For Blackwing Shura:

Is shura's effect for special summoning after it destroys an opponent's monster optional?

For Blackwing Armor Master:

When is the correct timing for using the effect (You can remove all Wedge Counters from your opponent's monsters to reduce the ATK and DEF of each monster that had a Wedge Counter to 0 until the End Phase.)?

Is it during main phases only or can i use it in the same battle phase which i put a wedge counter on a monster? －203.177.91.161 10:01, September 14, 2009 (UTC)
