CardMage is a Deck of Many Things tool and is part of the Grimoire App on the Apple App Store. 

Possibly one of the most famous magical artefacts in RPG games.   Huge rewards, but also huge risks.

This is a tremendously powerful magic item that comes in the form of a deck of cards, each one causing a distinct effect upon the character who draws it.  These effects can be either beneficial or baneful.

This is truly not for the faint-hearted.  Dare you take a card?

Traditional and Modern decks are included.  Cards can be flipped in any direction.

The Deck of Many Things is used under the terms of the Open Gaming License
