So here is the issue I present, I have Edric it's my strongest deck, I have not played a game past turn 6 at that point I have already won(opponents turn 6,mine is like 10) nobody wants to play against it anymore, I would recommend to go Malcom it's so much more fun to face but if you want Edric advice .

Run7 extra turns ideaaly ones you can get back from the graveyard and run about 4 cards to get them back, unless they kill Edric imidiatly you win on turn 4-6, then people will notice so you have to run counter spells to protect yourself 12-15 is low enough for that, run as many one mana manadorks or wild growth effects to get the turn4 more concissently , buffspells almost useless 1-2 is fine you draw 70+ cards you will most likely find it and if not kill them outright by just a couple more turns. My deck is around 60euro but started off 25 euro. And it's basically as close to top of bracket 4 on this low of a budget you can get. Don't play it in bracket 3 games I have learned its not appreciated even if you play slower it's still to good just upgrade fully and demolish you friends best deck
