I see at least four or five Tauros a day. Wingull is common as fuck here.
Slakoth is rare but not terribly hard to get (one spawns every one or two days in town here) and Ive seen one Chimecho.
Im pissed that Houndour is such a rare spawn here. Small town so we get literally no spawns for it and with it being recently introduced as a shiny Im pissed. As much as the rest of the team hates to admit it, I'm pretty much Mystic's shiny/100% hunter where I'm from.
If I ever visit the UK I'll trade you a Tauros for a Mime. Make sure its your oldest though for highest chance at a lucky.
Speaking of luckies, me and the girlfriend traded shiny Magikarps and ours both luckied. I was puuumped. Went from having a like... 29% (1/12/5) or something like that, can't remember) to 87% (11/15/13). Lucky shiny Karp. Bask in my glory.
