I have a heating blanket that overheated and caused a fire. The thermal fuse was covered with duct tape. Is that standard assembly for this kind of product??
You pay 3, and play the card from your hand. You examine all of your creatures on the field (only yours) find the card with the highest power. Creatures have X/Y where X is power, and y is toughness, these numbers are written on the bottom right hand corner of the card. (Note: There may be effects in play that are altering those numbers, such as enchanments equipmets, counters etc, you use the altered version of the number where applicable.) So find the one with the highest power, you may have cards that draw for the highest power thats fine, just read out the number. You then have target player lose that amount of life and at the same time you gain that much. If you have a good amount of swamps available to make sure you can play this card, and some strong creatures in your deck, or at the very least some powered up small ones, then sure, it can be useful.
I had a similar problem with a smoke detector which would go off when the steam from the kettle happened. The unit was 25ft away, and of course this is NOT smoke. Did some checking and found out that some of the detectors with certain components do this so changed ours and no problems since! Ours is not hard-wired but straight battery. Ours also has NO radio-active components in it, which we understand is the best one to have, and not just for the obvious reasons. You may have a similar problem to me because it sounds like your detectors may be reacting to heat [like the steam from my kettle] and not to a fire's CHEMICAL component, which is what a detector is supposed to sense! Take all of your detectors [the ones you took out and the ones installed] to a testing facility [check with your local council, fire authority, electricity authority, etc] for the correct one to go to, for your own peace of mind and for others who may have the same units, that COULD BE FAULTY FATAL in the event of a fire. I am sorry for your frustration and hope you get the right help, SOON!!
if you're that concerned wear safety goggles.. have you ever seen the poster CAROL NEVER WORE HER SAFETY GOGGLES. NOW SHE DOESNT NEED THEM. I have not heard that story you told but like I said if it scares you wear goggles lol )
