"randomly slice" Scimitar counter bug

Assassin, have you somehow forgotten that the Scimitar (Zantetsuken) is literally Odin's sword? Of course it's imbued with Odin's slicing mojo.

As for technical stuff, it just makes sense that any attack that removes the enemy sprite from the screen also prevents counters. That's clearly what Square was going for with these types of attacks, but cheaped out in the end with the Zantetsuken and probably just forgot about it with Antlion.
