For me, I chose Cyndaquil, and evolved it to Quilava... I LOVE Quilava so I gave it the Everstone... That's one Pokemon... Sentret/Furret (when it evolves) will be my main HM slave but I haven't decided on most of my team yet. Probably will include Lugia when I get it. (I'm playing SS) I plan to get the Pokemon like Sudowoodo, Red Gyarados, etc. but I don't think they'll be on my main team... Now that Togepi hatches with Extrasensory (I'm pretty sure that's what move that is) I may just raise that one. It's surprising how grat Togekiss ends up in comparison to baby Togepi. ^^
BTW HeartGold95, you should update your siggy... your team seems to be outdated on there!
Oh, and I must mention that I only started playing yesterday. (I have 3 badges so far)
