If you block Lambda's 236B and you know your opponent is going to IAD backwards > j.2D, you can do a dash-in 2C or IAD j.C yourself to beat her out of it. Due to the trajectory of the sword, you should run right underneath it for a free punish. If you keep blocking after she's done IAD > j.2D, Lambda should be out of range for 3/5C which means you get to punish a whiffed attack (assuming they did those moves out of range), charge your stock or do whatever else it is you Tsubaki players do. If she's close range and does 3/5C > 214D, you can do a quick dash 2A to hit her out of her 214D start-up for a another free combo and some more stock.
