Could anyone help me think of text for a continuous trap I'm making called Dragon Snare? The whole idea of preventing dragons from attacking or gaining control of your opponent's dragons is outdated, and that's all I can think of. Any help would be appreciated. Here's the art for the card if it helps. I was thinking of including gaining Life Points for every dragon your opponent controls whenever you activate the trap.

since it's about snaring dragons here is my idea for card text.
When this card is activated all dragon-Type monsters your opponent controls are switched to Defense mode and cannot change battle modes while this card is face-up. During your stand-by Phase, all dragon-type monsters your opponent controls lose 500 attack points, and when their attack points reach zero banish that monster, and if you do you gain life points equal to the banished monster's original attack points.
