I'm playing HeartGold, and I want to get a Kingdra. But I have to do a trade in order to get it evolved.... Here are the problems: 1) Nintendo stopped their DS online services about a year ago, so that means I can't trade with anybody at all? 2) Is it still possible, but I just need a Nintendo 3DS? I have a Nintendo DSi and I play HeartGold from my R4i flash cart. I tried to find some cheats that could just evolve my Seadra to a Kingdra, but there was nothing.
