Some random findings from Azrael's point of view to add.
Platinum's dash 2B can be countered with 3C or 6C on reaction because of the foot property. This probably does not work against dash 6A/5A or dash 5B unless Azrael's move becomes active first.
Random Mami in neutral or blockstring can be countered by 6A on reaction because of the body property that starts at 7 frames. Azrael can do 6A pretty late. High enough 6A counterhit leads to ~2k and weakpoint without weakpoints, all the way to around 4-5k with 2 weakpoints and near the corner. Sometimes if the 6A hits the later part of Mami, it will clash instead of counterhit so be ready for that.
Platinum's bubble reset in blockstring can be countered by forward dashing at the right ranges for a punish, or backdash for back to neutral. Example string being Platinums 5a>5b>3c>bubble or 5a>5b>5c>3c>bubble. Both are forward dashable on reaction to the buble startup. Nothing else seems to work reliably. The timing can be a bit tight on Azrael's part but the reward is a standard midscreen/corner bnb, 1,7~2,5k (3~5k corner) without weak points all the way up to 5k~6k with both weakpoints and BHS. Instant blocking 3C makes things a lot easier. If Azrael blocks the bubble and you try to dash 2B in, 2A seems to work decently.
Recklessly air dashing is really hard for both players in this matchup. Azrael's 2C beats any low airdash attempt but loses to high aproaches due to it's bad vertical range. 5B beats deeper j.B's but the timing is harder due to 5B having no head property. Platinum's 6A on the other hand really stuffs all the midscreen airdash attemps so that's not really an option. Instead, when Azrael gets in, he can op to instant airdash cancel his 5A or 5B in to a crossover j.B which can be a pain to react to and anti-air.
Just like most cast, Platinum's counter can be baited out by activating it with a 2A or 5A and then punishing with 5D/3D/6D counterhit which leads to 3~4k+ without weak points depending on distance from corner. He can also opt to get a phalanx stock by doing 5A>growler and then punish with a midscreen/corner bnb or a counterhit but the timing is tight. A swag way to punish this is also to do 5A into instantly cancelled slighty charged hornet or valiant.
If Azrael has Phalanx stocks, you should be really careful what you do on the ground. Any ground weapon load, wiffed b/c normal etc can be punished by a 9 frame startup Phalanx into BHS for 3.5k or Phalanx in to forward dash TK gustaf for free gap close and pressure start. Azrael needs to be slightly closer than full screen for BHS version to work, and somewhat closer for gustaf version.
