Best MtG Rules & Judging App – MTG Guide Review

TL;DR: Buy this app and MtG Trades (Same developer). Best money I've ever spent. Are you a judge? You need this app. It is the best tool I've ever used hands down. Are you the friend group's unofficial judge? This app is your best friend. It has everything you could want on more. If this app could do pairings I honest think this would be an all in one tournament tool. Unfortunately it only has every rulebook, tons of errata and reference materials, and a bunch of helpful tools for anyone who has ever judged in any capacity.
