Starting with 2 cards that probably will see a nerf, question is how would you nerf them:
Milva Sharpshooter – i would change it to only work with Cards that move units – so no synergy with Guerilla Tactics, because now it's so strong that it's the only playable leader. I know it didnt see any play before but maybe it just needs some smaller buffs like for example buff Vrihedd Brigade to deal 3 random damage when moved (targeted damage would be too strong) and create or change some other cards to have synergies of this kind.
King of Beggars – i would change it to remove Counter of UP TO 3, forcing players to actually think about deckbuilding instead of just jamming Savolla, it would also spread the power he gives if you played your Tribute cards in multiple rounds. Whether he would still need some power or provisions changes is debatable.
Small buffs to NG soldiers package:
Daerlan Soldier – power up to 4 from 3, provisions up to 6 from 5. Solid proactive 8 for 6 with synergies with Ramon, Vrygheff, Vreemde, and creating Soldiers pockets.
Alba Spearman – power up to 4
Recruit – power up to 4 and ability changed to work like Alba Spearman but with boosts.
Sweers – also boost adjacent Soldiers by 1.
Thinning autoincludes nerf: Mage Assassin provisions up to 5 from 4, Tuirseach Skirmisher provisions up to 5 from 4.
