When playing MTG I often encounter situations where I need to look up rulings/clarifications for cards. Imstead of having to type in the name of the card, I would like to be able to scan the card with my phone's camera.

Example:
- my opponent controls a 1/1 with hexproof
- I play [[electrickery]] for it's overload costs
- does it hit the hexproof creature?
- we need to look up rulings
- to the google I go (because it's faster than the companion app)
- I end up at the gatherer website entry for electrickery
- we now know it hits

Taking a picture of the card to have it's rulings displayed would make this process far easier, and would incentivize me (and other players) to use the companion for look up over other search engines.
