RedRaptor hit what I meant. If you do it fast enough F2 is free after a standing blocked ex dagger and jails them into standing, they can't duck or poke or anything. If you saw them crouch blocking during a block string you should "crouch confirm" (lol) so not to throw the EX dagger because it'll just wiff anyway.
But still a useful video, thanks for posting!
Nice idea Eddy. Just wanted to say that the opponent can't poke out after F2, 1, 2, 1+2, EX Dagger, unless they blocked the EX Dagger crouching, which doesn't happen after F2, 1, 2, 1+2 (either you jail them standing or the dagger goes over their head crouching). If they do try to poke out, they will just eat the whole F2, 1, 2, 1+2 combo again or a B1, 1, F4 combo. Backdashing into F4 can work, but IMO B1, 1, F4 is superior because it's guaranteed to hit and does more chip damage if blocked. Good video nonetheless Eddy.
