Forum:Attack the Moon! vs. Flip Rocks

Just a bit of curiosity, here; say I control both Attack the Moon! and something like... Golem Sentry. If I use Golem Sentry's effect to switch it from face-up ATK position to face-down DEF position, can I activate Attack the Moon!? Vorpal Storm Pony (talk • contribs) 19:29, November 18, 2012 (UTC)
