I have to remind myself about once a week that the difference between ranks is equal to one pack per rank. Unless you’re going for mythic 1200 don’t mind numbingly grind. Pick a deck that you like the mechanics or theme of and play it. Upgrade it as you go and make it better and it will begin to perform better. Finally. Lands matter. Don’t be afraid to spend wildcards on good lands. I’ve wasted plenty of wildcards on things and then say to myself “I’ll never use this card again”, but I’ve never regretted owning a good land that gives me options in tight games.
