@pastel cedar so, Ike. This mu I know is not good for brawler but it’s not impossible. I see what you mean, you were really struggling to get some good hits on ike because of rm8s camping. In these last few games rm8 is basically doing what I said earlier, he’s camping, letting you swing first or letting you over commit before making his move, and being the big sword man he is, he doesn’t have trouble doing that.
So Ike’s nair is crazy safe on shield unless parried, you were able to parry it a few times but not really enough to make a huge difference. One you’ve made that parry, you have to make sure you push your advantage to the fullest (I can’t really tell you how many times I’ve lost from making one mistake and dying off of one disadvantage state to characters like palu) That’s something I’d recommend, find a good ike (not rm8) and practice parrying his nair.
Rm8 in particular has a an ike who really loves double jumping to prevent being anti aired. In any other case, I’d say try your best to anti air ike before he can get into a position nair, but in this case that’s a little less applicable. So I’d recommend taking ike to a stage without center platforms so he can’t air camp as well (Fd, town, and kalos) Fd and kalos are also one of his worst stages because he can’t easily kill off the top as well.
