you don't need the cards to play the game though, you only need the cards if you win a prize, i'd hardly call the prize cards rare these days, they make heaps of 'em,
132 sets won are complete, they probably print 500 sets, a lot get used in frames or if you don't want a frame you can just get the team set on it's own, which I have, they send team sets in an album just like full prize sets, pretty cool.
so yeah, there are many more prize cards then people think.
just go in and pick a team, see how you go.
this week being a split round might be easier for you to start, you might be able to pick your team after the weekend and load up with all the high stat players of this week and top it up with the remainding teams to play next week.
top 4 game is by far the easiest to win, you only pick one player from each position, you just need the right combination of 4 players, bit like tattslotto.
