There's not really much to "farming" since RNG is the whole deciding factor of CA. If you want to survive while farming rainbow coins, use 3 units to get the bonus multiplier to 2.50, and keep switching units to get all your units having BB/SBB full. Eventually after doing this method for a while, you will meet Jin, the Gate keeper of CA and his henchmen's of Hadaron/Zedus leads with no BB match. Use 5 units and pray OFS doesn't activate. Then your day ends with whatever much coins you farm while cursing at every Hadaron lead.
