pokemon booster box sun and moon & Team Up Sleeved Pack Booster pack from SM10b Sky Legend (Japanese only) Pokémon Sun & Moon Base

Put a counter of that kind on this creature

Every Magic: The Gathering FINAL FANTASY Play Booster contains an art card (which you can learn more about here) or a non-foil double-sided token featuring one of the set's 23 full-art tokens or the emblem created by Sephiroth, One-Winged Angel on each side

Each iteration resets the board to its original state, so you'll need a way to get some value out of the loop

Next up is Yuna, Grand Summoner , who joins Tidus in the Counter Blitz Commander deck for Final Fantasy MTG

Not background necessarily, but some other line of text that says something along the lines of Whenever you sacrifice a Treasure token, give a creature a +1/+1 counter and trample until end of turn. That would make it a lot more interesting and powerful, but I suppose not every card needs to be great
