A ton of Iyo matches, very enjoyable stuff to watch if you're a Maki player. I'm still surprised when Iyo lands c.lp s.lk and doesn't combo into super when he has meter. I can't figure out if he's missing it or what.
Anywho, check out the very first match on that page vs Mizutero. vs Blanka and Sagat Iyo used RC Genko a few times to good effect. If you ask me it's especially good against those two and other characters that 'should' be able to handle you with their normals.
So basically what I'm saying is:
If Iyo does it, it must be Top Tier. Iyo is Top Tier so by extension his techniques are Top Tier. The logic is flawless!
