After using 100 tickets I ended up with almost half of the rolls being nothing but salt. Two of the rolls gave me new gold Knights and a new rainbow though:
Overall I ended up with one new rainbow (Viola), two new golds (Poinsettia and Money Tree) and six gold dupes (Toad Lily, Konara, Sneezeweed (bride), Luffa, Madagascar Periwinkle and Kalanchoe.
1% rainbows, 8% golds.
