For tactics page, just spend 100 coupons per day in the myoboku wheel (the chance to pick a 10 pack is not low) or wait foe konoha outlet where that pack is at 225 coupons (10% discount).

About what tactics to go for, if you are f2p and you want to be competitive with low cashers do not go for ghost kill, choose sun move or the other tactics with defense. The effect of +1320 resistance/defense for a f2p is way higher than +990 nin/atk.

Bro, i do recommend you not to buy Mood Scrolls directly from the shop or even in Treasure of the Sage .. You can get tons of Free Mood Scroll in events, just like the Great Plates event .. For Clothing, you can get it slowly by just piecing it thru redeeming fragments of available clothing in events with free points just like what i did with my other Clothings .. And the rest, follow what peoples said above me and you'll be fine and strong one day .. keep it up bro, good luck :D
