So with that, we ended up with our four game selects
The potential is there for this one in the synergy and value department, but how often are you going to want that over the existing options and beating your opponents' faces in with cheap/free Myr Enforcers and Frogmites
Its drawback may look like its very punishing and can allow the opponent to surprise you via a mid-combat spell, but I never really saw that scenario play out since its damage prevention ability is a a conditional static ability so as long as its on when damage is dealt, it wont be prevented. (Thank you, @fenaris!) It usually plays out somewhat like a colorless Ashenmoor Gouger / Chimeric Idol where you typically dont bother trying to block with it (why am I blocking with my aggro guys anyway?) and, if need be, you cast a spell pre-combat to activate it (typically I used a large coin, like a quarter, to denote whether it was on or off)
You may be familiar with Kira, Great Glass Spinner from when it occasionally shows up in Legacy or Modern decklists, and Jetting Glasskite is Kiras older, angrier sibling
