Mantis card game box

Remix of MrNiceDM's popular UNO box, but for the game Mantis (made by the creator of the Oatmeal, Exploding Kittens, Bears vs. Babies, etc.). This is scaled up from the UNO version to fit a deck of Mantis cards.

Use standard, not tree, supports with a higher angle (>=50) for inside the lettering
