I wanted to know at a glance how many and what Wildcards I needed to build every tier deck on MTGA, so I created a script that does the job for me. If anybody finds it helpful, I put the tool online for free at https://bestdeckforyou.pythonanywhere.com/.
It automatically exports your MTGA collection and it works for paper MTG, too. For paper mtg, you only need to write a list of cards in your collection and it
tells you how much you must spend to build every tier deck in most formats (Standard, Modern, Legacy, Pauper). Prices are taken from MKM trend, so it's very helpful for European players. I also added a tool to quickly estimate the value of cards in your collection.
The website is still pretty rough, but maybe it will help somebody.
