Oh my gosh, I have been trying to get that Lorna Shine for the longest possible time oh my gosh! I can't believe you are actually intending to give it away!
My strategy is not anything fanciful. It really is the down to earth method. Being not well endowed, I am unable to put in any form of investment into the game other than the initial USD$10. My plan is to just pursue for the higher tier as it will give more Loot Chest from the daily and the season quest. It is an inefficient way, but it definitely is still a down to earth way. I know there are people that snipes and sells the cards, but I dont think I might have the time to do those as I still have to juggle between studying and working. So yea, nothing fancy, just a down to earth way of climbing to the higher tier!
