Forum:Royal Oppression vs. Mist Valley Apex Avian and Mist Valley Thunderbird

If my opponent activatessss....I donmn't know, Smashing Ground, and I have Mist Valleys Apex Avian and Thunderbird on my side of the field, and I decide to use Apex Avian's effect in response to Smashing Ground, targeting Thunderbird, then, with Thunderbird's effect, it Special Summons, and my opponent activates Royal Oppression. I'm pretty sure I can, but just to make sure, can I use Apex Avian effect again, and therefore, creating a lockdown from my opponent activating s/ts?--Yugioh DED (talk • contribs) 20:08, July 24, 2010 (UTC)
