Well, I've been playing with a lot of better players, and I improved very quickly because of them.
terry, romc, Prinny, and Munsu mostly, if not always.
I found that most of the tactics that work against better players.. don't work on the newer players who mash.
Frozen, I'll tell you an easy counter to the predictable obento setups: throw.
If you hit them with 2a and they block it, they have frame advantage, and would be the one throwing you while the obento blows up wastefully.
In normal 2a/5a tickthrows, you mixup your 2a/5a and your grab so they don't know which one you'll use. If they guess wrong, they'll either get poked or thrown.
In an obento setup, if you throw more than one 2a/5a, the obentos gonna explode and you're not gonna get your tickthrow (but a combo if you use another attack).
Resetting the obento is not something I really recommend until you train them to block. Besides, it's better to try for a combo instead of just a weak throw.
Chibi's examples were the ones that were the most accurate (completely accurate actually, but it doesn't sound right saying it that way).
Look at your "wakeup reversal and wakeup jump" that's already a 50% guessing game.
The reason I still say Kohaku summons are superior is because I've found a setup that's heat-safe, shield/ex-shield safe, EX reversal safe, backdash safe, parry safe, and jump safe all at once, where you can punish them with either a throw, a hit or two, or even a full BnB depending on which one they do. You also get a crossup if they block (even if it's extremely easy to block).
Another setup that assumes they'll block that's harder to block is there too.
I don't know the potential of obento setups as I've never used them seriously, so I'm not gonna contradict anyone but agree with myself.
