To continue PEEF's trend of giving advice to a superior player, I think the way you handle lasers could improve a little, Wobbles. IIRC, Shiz and PP trapped you in your shield a lot with lasers, but Falco shouldn't be able to do that to ICs very well. For one thing, I don't think you use ice blocks often enough; they never lead to much directly, but they do interfere with Falco's momentum. I also want to note that while you make good use of wavedashing into lasers and having Nana fsmash, you can also do move forward -> pretty much any ground move or ice block, as well. I personally like walk/wavedash -> ice block, as it sends a projectile towards Falco and also immediately desynchs you. Ftilt is a good substitute for fsmash for the times when fsmash might be a little too slow or when you want to commit to something less laggy than fsmash. I also like having Nana run forward and dash attack after Popo takes a laser; it reaches decently far and can combo into a grab. Choknater's blizzard trick (I'm going to start calling this CBT since I don't like typing that whole thing) is pretty good; I no longer agree with my old complaint that you get punish hard for doing it if you guess incorrectly, because you can just short hop forward and blizzard on reaction to a laser. No guessing is necessary, although blizzard does admittedly come out a bit later this way than it does otherwise.
The next part of this post isn't directed at Wobbles in particular and is mostly me brainstorming or going over old ways of dealing with lasers. One thing I just thought of would be dtilt through lasers. Dtilt is a weird move that can combo sometimes, but the semi-long duration of the move limits its use as a combo tool. Of course, if only Nana dtilts, as she would if Popo takes a laser, Popo should be able to combo off of it, maybe even into a grab. I'm pretty sure this would lose to CC'ing at low percentages, though.
While CBT is good, it would be especially nice to have a way of having Nana blizzard forward while remaining on the ground. One thing that I've probably mentioned here before, that I'm almost positive I've tested (and I'm almost positive that this worked) would be to walk/wavedash forward and input a blizzard command while Popo is in hitstun from the laser. This should be good and I don't know why I don't do it.
Another thing that I don't think would work, but want to check anyways would be doing the synced blizzard on the ground backwards and having Popo take the lasers, so that Nana blizzards forward. A couple ideas about accomplishing this would be to either do a long wavedash forward while facing backwards and doing blizzard or wavedashing forward and turning around and doing blizzard. IIRC, Nana always does the synced blizzard in the same position with respect to Popo, though, so I don't think my ideas for getting Popo a bit in front of Nana such that only he takes the laser would work. I might be wrong about that, which would be nice.
