Hey everyone! so yesterday my brother and I had a duel and we got into a ruling about horn of heaven on pegasus and it going to the spell and trap card zone if you know the proper ruling for that please comment!
But I did find some intresting rules on the crystal beast's like never before like if there set and someone uses dark hole there effect would not activate,but heres a link to some so we dont make ruling mistakes link here;http://yugioh.wikia.com/wiki/Card_Rulings:Crystal_Beast_Amethyst_Cat

Hope you enjoy reading them thanks.

Pegasus does not go into the backow for one reason: Negation of summon.

When a monster summon is negated it was never considered to be on the field, so when the card says "If this face-up card is destroyed while it is in a Monster Card Zone,..." It was never there so it cannot get this effect. And you do not get the first effect of putting a crystal beast in your s/t zone.

Thanks! That helped sum up alot
