Gabe is correct. When banding in 4 characters with multiple abilities the normal order of operations must still be followed. So for example if there were (1) special abilities that let you play a card, (2) weapon class enhancements that let you draw, (3) banding, and (4) choose the blocker. You would have to activate them in that order. So it would look something like this:
1,1,1
2,
3,3
4
This would mean that Ehud's choose the blocker (4) would happen after Miriam's ignore (1), therefore, an Egyptian could NOT be chosen.
