Nope no street passes at all. My son is the only local player I know and he's not enough to get me anything. Cresslia has not joined me either. No idea how many times I cleared the area. I have encountered & Battled Suicune 19 times.
I still don't have all the Legends yet but got bored going back to the same areas over and over. and Suicune has mocked my every attempt to catch! I have failed 19 times to get him to join my team! I have 3 Rayquaza and 2 Heatran but Suicune just is stubborn as can be.
Some folks want to remember a certain day, a wedding day for instance. so to remember it we get cards, flowers, cakes, whatever to show the that special someone they fondly remember the greatest day in their life. Honestly if you don't get it, you won't get it. So explaining it is wasted time Ludwig.
