I have found this post on a thread on Reddit MagicTCG on how to utilize your spare Fatpack or Bundle cardboard box and turn it into a stand to place your smart phones and angle it to properly video your board state.

You can check the quick and easy steps on how to do it here below:

Here is an actual example of the setup.

That is one clever way to multi-use your fatpack box aside from storing your Magic: the Gathering card collection or your EDH deck. This is very suited for an improvised online multiplayer gameplay especially in the Commander format. Your group can just open a video conference wherein you share each of your respective board scenes and announce your spells and activation via the group call. You might need a headset or headphones attached for those so it will be clear.

Leave a comment if you have tried this one at home guys.
