So I thought it would be pretty cool if the Planechase cards (the locations and events) were added as a set or as a feature allowing you to use this app as the Planechase deck. Any chance this is possible? I'm thinking something similar to try play or something in the life counter.
WotC is not interested in you using this app as a Planechase deck, they want you to buy the deck. They specifically prohibit proxies. I can only allow Planachese cards as part of Card Database, as this is within legal regulations of US copyright law. Can you provide textual game rules for the cards? I could only find the scans which is what is not allowed by WotC...
I'll look for something. I know the very basics of the rules, such as rolling a 1 is Planechase and rolling a 6 is chaos. Also know that the first roll per turn is free, only as a sorcery, and each roll after costs 1 extra from the previous roll. As far as card specific ruling I'll have to search for those.
Also I can see why they don't want people making their own Planechase proxies. At 65$ or so for each of the 11 sets I can see why they would discourage proxies.
So here are the rules provided by WotC https://www.wizards.com/mtg/images/daily/features/feature51_Planechase_Game_Rules.pdf
Here are some specific rules provided by MTG Salvation http://mtgsalvation.gamepedia.com/Planechase_(format)
I was thinking about rules as in oracle text per card.

This is the gatherer link to the extended list of the Planes & Phenomenons. Does that help?
EDIT: it seems linking does not fully achieve perfection. In any case: advanced search on Planes & Phenomenon in "types", make sure to mark "special cards".
