Forum:Crystal Beast Lock Down?

I can't find a ruling that clarifies the result, so my friend and I had an argument with his Crystal Beast "Lock down" strategy.

So in the first turn, he summoned Sapphire Pegasus, and then placed Amber Mammoth in his spell and Trap Card Zone. He also activated Rainbow Ruins and did a bunch of moves that swarmed the field with Crystal Beasts. When my turn came and I was going to attack, he said I was already "Locked", and I should not be able to attack since Amber Mammoth will prevent me from attacking any other crystal beasts;

Amber Mammoth: When a face-up "Crystal Beast" monster you control is selected as an attack target, you can change the target to this card. If this card is destroyed while it is in a Monster Card Zone, you can place it face-up in your Spell & Trap Card Zone as a Continuous Spell Card, instead of sending it to the Graveyard.

He said he would direct the attack to Amber Mammoth, and since Amber Mammoth is in the spell and trap zone, the attack will be invalid. Although it was ridiculous, it somehow made sense, like the "Grave keeper's Servant-Dimensional Fissure Combo".

I'd like to know the real results, please.Dark.armed1330 (talk • contribs) 13:56, February 10, 2011 (UTC)
