Hey guys, I currently have enough lab coins to buy a hero. My first pick would normally be Shemira, but she's out of stock for the next 3 weeks, so I was going to buy another hero in the meantime as I'll be able to save up enough to buy her when she gets back in stock. I'm currently stuck between Nemora, Thoran, Skreg, Khasos, Wu Kong, and Arthur. Nemora, Skreg, and Khasos are all gated by missing copies (4 or 5 each) and lots of fodder, and Thoran only needs 1 copy of himself and one legend fodder to ascend. My Wu Kong is legend with no current copies. Would it be best to go ahead and get copies of the normal 4 to save for later, begin buying shards to buy Arthur, or buy Wu Kong to get him further?
