No drastic changes that may just make this card broken or trash, but something quite simple that I can see its quite silly, and that is its veteran condition.
As many may know it becomes veteran if it is the first of that card spefically you deploy in a battle, and that just leads players to put only 1 in their decks as it is not worth to put more than that.
So I suggest a slight buff for that, an aditional condition for it so it can be played around and used as a Limited card instead of a Elite card (realistically you'll only use one)
so here are my ideas besides the base condition:
1-Extra condition: can also trigger if there is another japanese fighter (could be enemy or ally, this could be modified).
2-Extra condition: can also trigger if the enemy HQ had recieved 4 damage, similar to the panzer III-J LATE.
3-Extra condition: can also trigger if you've lost a credit slot this turn.
Maybe this is just overthinking and is not necessary as it is good as it is, or could be a good adjust for it.
this card does not need a buff lol
