there are 5 starter decks each with 30 cards. They are playable. I actually cracked a few of these and ended up keeping them for deck building. tricky m12 Mono themed very basic. there are actually 2 different per color so im not sure which is which. Like there is a mulligan style blue deck and a flying creature blue deck. You could end up with one of those mechanics to play out. Same goes for the black one there is creature kill and one is discarding stuff etc. So 5 totally different decks great for beginners.
