So i was trying to build a Ud deck and i don't know wich runes fit the most my deck, i really like the ireguards and the goblin king and i think it's fun to play imp vixen and soulthirster, i didn't put grimlic because he's expensive and whenever i have money to deploy him i usually put other runes in play so i prefered to use a cheaper unit, for the spells i know demon call can be considered a wasted spot sometimes but can also be a lifesaver others, split personallity and fading recolection are usefull to handle things that are generally broken. And that's about all i know so any information would be very helpful
go for nefari shock box instead of bloodbows. take out bok mistress and fire dancer for x2 succubus take out manslayer/adept and priestess and use deep elf mercs temptress and siphon for either deep elf fanatic and a minotaur stoker or x2 of either one instead. Blinding spell, fire ruby and tinder box are meh in the bg. I'd replace with dark pact, mandate of sheoul, and another punchusion. Generally you want to go with champs that will work with each other so you use things like superiority and demon call. Knowing what works good where is also a big part of bg making. Don't try using 1 of a lot of runes but instead aim for trying to get x2 of most and maybe only 1 of things like the fat gluttony guy and vixen. You don't have to take my suggestions in changing out runes because it's all player preference
