Sec Create a 3/3 black Dalek artifact creature token with menace
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)
We havent done a deep dive in a while, so thought it could be fun to do some detective work while pondering how the new abilities could change the game
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
So with that, we ended up with our four game selects
