I like the premise of Killbray's Better Starter Decks, a Revised Core Set-based series of deck which has absolutely no overlap no matter what amount of players and team compositions ("pick-and-play"), yet better than what the official manual provided
If you want to make sure you snag a digital promo code, Secret Lair drops and prerelease packs older than Aetherdrift are good bets
Honestly, wed be shocked if it didnt cost a mortgage
Expect 60 or more rares and mythics across the box, with a much higher proportion of foil and special treatment cards than a play booster box delivers
In short, spot removal spells tend to fit better with the plan of creature decks than board sweepers do
That means that all you have to do is make sure you cast a few spells beforehand, and suddenly youve got an army of just this one Creature to take out your enemies with
