I wouldn't even make this a piece of equipment. As a regular artifact with the text in "..." this would be fine (though maybe rare). I'm really enjoying your reinterpretation of old spells in new forms. Is something I have toyed with myself with Lobotomizer and Flaming Effigy. There is a lot of design space available with such reinterpretations. Keep up the good work.

Thanks for the complements.

Since everyone seemed to like Shrapnel Launcher, I wondered if I could do a spell everyone knows and loves in the form of a reusable equipment. This could be considered a prototype. Any suggestions?

If you want it as equipment it shouldn't be a scepter as they are traditionally activation artifacts. Deconstruction Orb maybe, Deconstruction Probe ???

This doesn't really use the equipment-ness. It could just read ", , Tap an untapped creature you control:" Similarly with (((Alarm Bell))).

Yeah, most equipment has some form of effect on combat from providing evasion, to pumping, to pinging, tapping, etc. These just don't really fit as equipment.

Changed it to a creature, as the first attempt at green artifact creatures.
