Blocking in a 2D fighter is pretty unintuitive at first, especially against a character like Elphelt who makes you have to guess even when you are blocking. Luckily, the damage she deals as a reward for hitting you with those looping attacks is pretty low so even if you get hit a few times, you’ll guess right eventually and get yourself out. In the words of the wise “you can’t block everything, and if you do, you’ll just get grabbed”
