It seems so innocuous, but this thing is a monster. Forget, for a moment, how well this thing goes with Affinity or any number of aggro artifact decks in standard or extended and consider this thing in legacy or vintage. For example, if some of you recall, there was a combo deck not long ago that was relatively powerful and fast that relied on getting a Sensei's Divining Top into the bin and playing 2 other Tops, over and over, with Locket of Yesterdays to up the storm count to some arbitrary number or gain infinite life with something like Leonin Elder. It seemed like a clunky combo, but it worked very well and with consistency. With this card, you only need 2 of the Tops to go off instead of 3. Nevermind the bevy of other combos and synergies this thing allows for. Honestly, if you fun anything with a significant number of artifacts and can afford a splash of blue, run a full playset of these.
