Idea Claymores / Mines

I have been thinking on this topic for a little while now, and I think this should be a very good feature added to McWarZ. What is this feature? Well I'll tell you. Claymores or Mines call them what you will, but they are a kind of explosive that you can place on the ground. Something like a Carpet in Minecraft could be used for this. You could place them down like a normal block and it changes to the color of the block under it as much as close as it can. Of course this could be a very terrible thing to do, as people could place claymores around various and popular logging spots, I guess you could have a limit of how many claymores that are yours can be on the ground armed at once. I also think there could be a feature so it can't be a threat where you place one down when you're about to die it could be added where it takes about 2-3 minutes to Arm itself so you can't just win a fight like that. Give my some insight I think this could lead somewhere!!
