Forum:MST: 2 questions

1. Does anyone think this card should at least be semi-limited?

2. Can you activate a face-down MST during your opponent's turn when he/she sets a card? I don't believe that since it does not start a chain. You can only activate it when your opponent activates/Summons/enters a Phase that is appropriate to activate MST (Standby, Battle, End), right?--Yugioh DED (talk • contribs) 17:17, July 13, 2010 (UTC)
