There's not many Pokémon left to cover for 5th gen now, and I'm pretty sure it'll end soon for this generation of POTW. So yeah, if you just figure out what's already been done, you'll easily see the few left.
(And as a side note, most of the POTW entries are fully-evolved pokes, so there aren't many left at all.)
I still stand by by my decision to combine the Lumineon and Luvdisc PotW's, or at the very least combine Ditto/Unown/Wobbuffet due to either identical movepools or incredibly shallow moves.
This is done in order to conserve efficiency.
Can Suicune please be the Pokemon of the Week for the last week of August? Please? Pretty please?
