*Pushblock the first hit. Not sure where Geekboy is coming from, because to pushblock the second hit, you have to guard the second hit. Most cross-ups get you by the second hit and if they don’t, they’re out of range for a third guessing game anyways.
*Whoever said blocking high->low loses to double triangle-jumps needs to work on his reaction. A second trijump is slower and more obvious than the opponent attacking low from the first trijump, so you should actually be able to block it on reaction.
*In my experience, blocking high->low works on most Magnetos, a good portion of Storms, but very rarely on Ironman. This is because Ironman’s most common trijump is sj.LK, sj.d+HP. If you block low for the second hit, you eat the sj.d+HP, which is all he really wanted to land anyways. And unlike Magneto, Ironman can land fierces/roundhouses in the air without causing Flying Screen, and lead into infinite. Blocking high->low might not work on Storms that go for the infinite. Also, Storm has probably the best horizontal range in the realm of trijumps. Combine that with the ability to float to add in more high attacks, and you have a trijumper that more than makes of for speed compared to Magneto.
