Again, I'm no Hylian or Lain, both of whom have a ton of mu experience, but I'd say out of all the ICs matchups I have most experience playing vs pika. I played countless times vs all the pikas at the pika house, ldpk (who is a PR'ed pika), FZ I had a MM against along with an extraordinary number of friendlies, Kenny I MM'd twice, Leaf I played a number of times, Pharrox, Mister_E I played at least 2-3 times vs his pika, Artemis, and PikaPika!.
I really feel that if the ICs know what they're doing pikas have to strongly outplay the IC player in order to win. imo the ICs can outcamp pika with desynched IBs and/or properly timed attacks to negate jolts (which is not difficult to do, and most of the ICs attack can stop a jolt.)
And when it comes to approaching, if the ICs can find one read on you, you're in trouble. Because if the ICs know what you're planning to do when you get close, you're getting grabbed.
