About that you need to keep the field clear of opposing allies while using (Gotten Gains) for extra benefit and wait until you get (Nathanias, People's Champion)
Or (Oliver Fagin)

T1: sac
T2:use (Layarian Diplomat)
Or (Layarian Knight) if not use (bad santa)
T3:use (Aldmor Artisan) if you didn't find him use either (Aldon the Brave); to boost your allies attack by 1or (Sword Thief) to disable opposing ally
T4:use Ill-Gotten Gains if you have (Aldmor Artisan) it will cost you 2 cc then you can use either 2cc ally or bad santa
T5: you have X4 (ankle breaker) you should find one of them and use it either to disable opposing allies or killing them or you can use (Braxnorian Soldier)
T6:use (Viska, The Scarlet Blade) if not use any available thing cause there's only 2 copies of viska
T7: you can use either (Nathanias, People's Champion) to get extra ally on field or (Oliver Fagin) to place opposing ally with cost 3 or less to your hand

That should be enough to kill opponent keep sacrifice every turn to get a curtain win and about other cards (sever ties) to destroy an important attachment I usually keep it against warriors to destroy enrage and (A legend raise) to help disabled or weak allies both (Sinkhole)
(Garth's Concoction) to kill allies with ability attack helps with stealth units and (Groundshift) is useful complicated situations I have multiple choices in every turn hope these informations are useful have fun.!
