Well here is another one that is fun to use that a friend suggested me:

And the talents:

Basically an ignite/poison team who is mostly immune to control, since minato and obito avoid 1st turn mystery and roshi is immune altogether. Thus the imobile chase should be triggered every round. Roshi smashes barrier ninjas provided they did not kill him round 1 and has more initiative than mabui in 1010 lineups. Stil not really a f2p lineup, but cheaper than getting susanoo itachi =P

You can try the following lineup:

SN - Minato -SN clone

Kgaara - Earth main - x

x- x -x

Summon: Ninja cat

Chase: low float -> repulse

Talents: 3-3-4-1-2

Basically your 2 dps ninjas are SN at first, then minato after a couple chases. You have minato's skill as a move 1 interrupt and he is protected by SN clone. Earth main's mystery wil remove bad stat effects every odd turn and he should protect your ninjas as well as possible.

Problems arise if you do not have gaara's barrier, but you have some manner of CC in it to try and survive without it.

That was during anniversary so it might cost more now.

As for how we got them so quickly, many players recharged, others saved coupons since we knew we would get them for 3.0 and a very casual spender (20-30$ per month) can save up to 6k coupons per month.
