Buy this App, You won't regret it – MTG Trades Review

TL;DR: Buy this app. If you want rules or judge info, buy the companion app MTG Guide. Best money I've ever spent. This is literally the best trade and card reference app on the market. It updates constantly and quickly to add new cards. Has all the info you could want about them. Powerful search and sort functionality for lists and sets, wants lists, trade calculator, and loans tracking. I've even used the lists for decklists before because it's so easy to use and track prices.
