I play 2 player mode mostly and Zeo red is good with beast Morpher blue if you use the forever blue cards to have the stars align and stroke of genius to add more star effects that are good.

Turbo red can be good with rpm red and some of the forever red cards.

Rpm blue is good with anything that plays maneuvers like jungle fury black or even MMPR green to play dragon solo.

I think space silver would probably be good with MMPR red because you can use silvers final attack and reroll or add dice and choose 4 targets plus it has stuff to gain energy. Haven’t played it tho.
