I noticed that imitator is now available for 159 gems in the Pvz 2 shop. I have 71 gems. I wanted to ask: -what are the best levels for gem farming? -when does this sale end? (Will I be able to afford him with gems or I don't have enough time to collect the 88 remaining gems before he's for 2.99$ again?)
