So it seems to be as I thought: a "mash up" of excess cards from Japan, including recent deck promos (Ninetales-EX, Vaporeon-EX, Jolteon-EX, etc.), the Pokekyun Collection mini-set (the "second Radiant Collection"), and most likely the Premium Champion set (the Articuno full art reprint from Roaring Skies , the Basic Energy)

Whenever any opponent loses exactly 1 life, it grows with a +1/+1 counter and lets you exile the top card of your library to play later
What I did instead is basically say "let me show you this really stupid thing this deck is capable of doing" and before discarding, I showed them Myr Incubator and explained how an all-in artifacts deck can pop off with it
