I think he's definitely got the best head for numbers. Toast is probably better with deductive reasoning, I've seen Sykkuno get lost with putting things together but that could just be his lack of patience. Michael has brains, but also the know-how and get-it-done attitude that gives him a step up in real world competency. But if I was putting money on a competition of mathematics, memorization, or pattern recognition, I'd bet on Sykkuno.
I'm a bit oldschool so I thought of blues, they were pretty much just an earlier version of the same thing but they were born among regular goblin populations and normal goblins often hated them so the few that survived till adulthood tended to be solitary.
I'm the opposite of Syk, I say the first half outloud while using picture memory for second half. I've been told my brain is backwards XD (asa joke obviously)
visual memory can help remember the first few numbers while saying the rest out loud can help you remember those...so you combine them (At least thats how it works for me)
