Hello again!

Officially just got started on my Small LC collection, with deciding to hunt my 2 favorite seasons: Dino Thunder and Wild Force, managing to get a hold of the following haul today from a lucky hunt:

Dino Thunder Yellow

Wild Force Lunar

Wild Force Blue

Wild Force Putrid x 2 (the urge to have 2 was too strong, applies to any army builder, but these guys were my favorite Non-Putty Foot Soldier)

(I do Plan to chase the whole Wild Force team, since I got a better start, and keeping in mind that it's just 4 drip feed rangers, Maybe Jindrax, Toxica, and Zen Aku(provided those villains ever get figures(trying to keep things small)

With my question above, I wonder what qualifies as the "Dino Thunder Team":

Specifically, would be getting Red, Blue, Black, and Mesogog be enough?

I ask since all 4 Yellow of these figures make the core trio, the Mentor and Main Bad Guy

Not to mention, I'm hesitant to try getting White, as he's just too expensive online compared to the other 4 Dino Thunder figures I listed.

Any advice from fellow Dino Thunder fans and fellow LC collectors
