That was too similar to what SW said and what I did too. I'm doing lightning scar easy on level 132, and with extreme farming (up to 2 million cash in rounds 85~95). I've now gotten 12 ray of dooms and 13 temples. Though this time I didn't use 0/4 snipers, since I got a fully sacrificed temple by level 63, and loads of space for banana farms.
