WITCH and DRAGON for sure, both are mythological. One or both of EGYPT or CHINA, as both have deep mythological traditions. Those would be my picks, but it would be a very lucky board if all four were red.
Other possibilities:
SOUL - more spiritual than mythological, but often considered not real
THEATER - like the ancient Greek theater where Gods and monsters appeared
NOVEL - could be about mythology, but I think this connection is a lot weaker
LUCK - ruled by the mythological RNG
TEACHER - to keep the mythology alive
So I'd say to select the two monsters first, then the two countries, if they're all ours, great, if not, hopefully only gray, and then we'll have to find the other two out of the rest.
Dragon(s) are mythological creatures, I'd go that one second.
Witches are... fictional. Mythological, I guess? Makes sense as third. That, or Soul- many myths involve the afterlife.
Other possibilities: China has myths, there's Cinderella's Glass slipper, you could read about mythological stories in a Novel. I prefer Egypt, Dragon, Soul, and Witch though, in that order.
