What is Mystery Booster? It's an awesome experience with the feel of a "Chaos Draft" that uses multiple Magic Draft Boosters from different releases but bundles the cards and variety you'd experience into one amazing package. The set itself contains a whopping 1,670 reprints from across the game's history, plus 121 copies of something new and surprising—R&D Playtest cards you won't find anywhere outside of Mystery Booster: Convention Edition. There are so many cards packed into the possibilities, you could fill an entire eight-person draft and not see the same card twice.
Cards in Mystery Booster have the original set symbols and numbering of one of their printings. The only difference is a Planeswalker symbol in the lower left corner, like what you find on cards from The List in Set Boosters.
Each Mystery Booster: Convention Edition booster pack contains fifteen cards—fourteen from the gigantically awesome main set, and one from that "something new and surprising" group of R&D Playtest cards:
• 14 Cards from the main Mystery Booster set
• 1 Card from the R&D Playtest cards

I guess the smell is offputting
Size: 2-pack, Style: Duo
My dog loves chocolate stuff. But for some reason, wasn’t a huge fan of these balls. She played with them a little bit, but they’re not her favorite.

Great ball!
Style: Recharges, Size: Medium
The dog loves chasing it! Walks around sqeeking it all the time. And bonus, I can see it in the middle of the floor when I get up in the middle of the night so I won't unknowing step on it.

Lil boy's favorite ball
Style: Recharges, Size: Medium
The squeak gets my little boy every time. The glow factor is under par. I mainly get it because he also enjoys the brighter colors. All of the others be trying to get his ball. Good product just wish it would glow better because our park times are right around sunset.
