Would you mind giving me a pointer? I have a hard time against him because GA's ranged game doesn't really discourage mindless rushdown, and I haven't found a good way to deal with armor grabs from Grundy. I feel like GA basically can't pressure Grundy on wake up at all, and that's kind of how Ga works:/
Here's what I was trying this weekend, and had alot of success with( I don't think it's 7-3 arrow, but I think it might be 6-4 maybe, maybe even, just because of grundy damage potential. )
You dont' wanna pressure him on wake up at all, because he will fuck your life up.
Bassically DB2 move is your best friend in this match up, you wanna play it at just outside of sweep range.
From here you can DB2 on reaction to WC ( DB2 will get you away from WC at close range as well, Even D1~DB2)
You have to think of yourself as a little mosqito in this match up, you're not going to really be able to pressure him because of his Armor trait and WC, so you have to be in and out and stay safe with the DB2 escape option.
DO NOT FIRE ARROWS AT HIM, he can MB swamp hands or just WC you on reaction, then you get to say night night.
If he does try meter burn swamp hands, at the right distance away you should be able to dash in d1~freeze on block.
You wanna be in and out looking for D1~Freeze when you can, be carefull with your cross ups as well, don't over use them, his AA throw is insanely good and seems to beat out J3 ALOT.
If for some reason he goes for his super, which he may because you will be annoying the shit outta him lol, stay grounded and don't run away, just D1~arrow him over and over and he won't be able to do a thing to you,
if you are patient and stay in that range there is really not alot he can do to you, and you will slowely chip away at him.
