Yep you'll be good especially since you have 2 oodachi. I just noticed you mentioned " equipped by only defense troops". For Oodachi, you could try equipping them with gold elite troops, and for the tachi, gold light or heavy cavalry.

I feel that defense troops only help lower the amount of damage done to your troops and not so much the swords. The damage done by the yari on the swords is generally fixed. At level 99, you've probably gotten to the point when enemies do negligible damage to troops. So you might as well equip with troops that have stronger attack power, which will increase your chances of OHKOing the yari.

You might even want to try gold catapults for your uchi and waki as well. If you get lucky, you might get rid of yari's troops before the actual battle starts.
