I've been playing some Ger/Fin Discard lately and oh well... the deck is horrendously bad right now...
But it doesn't have to be!
Hear me out...
What if we changed the wording on 169. Grenadiers to read "The enemy discards a card at random when giving an order", so that it's effect resolves immediately?
That way you’d be able to get at least some value out of it, even if it’s taken out the turn after it comes into play (e.g., by Extended Barrage).
