My first attempt was pretty laborious
The first player wanting to occupy The Iron Throne (before that it doesn't exist), needs a card that straight up gives it to him
In general, also try to have four copies of each card you definitely want, so they come up more reliably
I wish Archetype of Finality wasnt that just seems too high king-saproling on Torbran the exterminator 6 years ago These might interest you: Gratuitous Violence , Berserkers' Onslaught , Quest for Pure Flame , Insult , Angrath's Marauders , Wojek Embermage , Knollspine Dragon , Spinerock Knoll , War Elemental , Elemental Mastery , Balefire Dragon , Siege Dragon , Glint-Horn Buccaneer , Firebrand Archer , Dagger Caster
Continuing that, the mana cost combines the components, and a card asking for Destined to Lead's mana cost sees 4BG
