Demon decks used to be a thing, but also used to be the 'meta' deck as well. Since then, demonshield and DEP have been nerfed so they demon synergy is much less, and it is no longer worth missing out on non-demons in a meta deck, nor is it entirely worth running a 'demon deck'. It would be great to get more demon only synergy in the future.
I only recently started playing Blood decks, so I'm still figuring out myself what works best but here are my decks. Both decks are very exo/leg heavy. The heaviest of any UD theme. x1 Angel of Pain x2 Blood Abhorrent x1 Demonologist x1 Demonvein Vampyre x2 Hekatian Arbiter x1 Hekatian Bloodguard x1 Korona x2 Naria Mindtap x2 Naria Ragevine x2 Seeker of Blood x1 Boundless Enthusiasm x1 Drain Vitality x1 Fading Recollection x1 Fiery Ambush x1 Mindslicer Boomerang x1 Purefire x1 Rain of Blood x1 Sacrifce x1 Retribution x1 Shatter x1 Split Personality x1 Superiority x1 Griefbearer's Fountain x1 Mark of Sheoul x1 Demon Shield x1 Widowmaker And another Blood deck focused more on Blood Magic x2 Blood Abhorrent x1 Demonologist x1 Goblin Gloombringer x2 Hekatian Arbiter x2 Hekatian Bloodguard x1 Korona x1 Naria Mindtap x2 Seeker of Blood x2 Sheoul Magus x1 Boundless Enthusiam x1 Demolish x1 Drain Vitality x1 Fiery Ambush x2 Maddening Echoes x1 Price of Victory x1 Purefire x1 Rain of Blood x1 Sacrifice x1 Split Personality x1 Globe of Deception x1 Griefbearer's Fountain x1 Mark of Sheoul x1 Demonshield
@Xzablaz Here is my maxxarek deck that i've been using since the patch. Champions 2x Deep elf priestess, Magical Attack & Multiattack 1 so you can run her at the ever important 65 nora mark. Demonologist, drain and bleed. one of UD's best and only ranged units. can also heal other units cause of bleed Grimlic Fire bomb 3 and Regeneration 3 (We all know why he's in there) Maxxarek, Set Ablaze and Portal. Portal makes for good escapes from a bad situation and good for telling people to ******** away from your font, Set ablaze is awesome, nough said. Nefari guardian, Resistance physical 2 and bodyguard. Good for letting key units stay in the fight that while longer Nefari Informant, Shadowspawn and call of the hunter. Stealthed surprise relocation can really Firk Bane Shift up and he costs under 65 Pincushion. Damage shield 3 aura 3, Points and laughs at literally everything it fights against that isnt a passive damage machine or a bomb spammer Sheoul Demon, Blood rage Stat bonus speed. as an early game draw he can carry you like crazy and get kills effortlessly to quickly get out dark summons from Maxx Sheoul Magus x2, Abuse Charged and Life Siphon. Perserverance and his self healing potential makes him an extremely disruptive champion and theres a strong possibility when hes almost dead hes going to be able to be used for retribution or sacrifice which does wonders for his efficiency. Sheoul Monstrosity x2,Call of the hunter, Crushing charge. Seriously the most under rated champion in UD. can crushing charge through an opponents front line and constrict a range unit and totally lock it down, also pretty tanky and can relocate champions. Siege Monger, charge 3 and seism. He has seism that's the only reason i run him. Vothsair Reaver, Hold the Line, Blood Frenzy 1. Oh boy is this guy tanky, take him to a choke point hold the line and watch him firk Bane Shift up. Also see Sheoul Magus regarding Perserverance. though he's faithless so he needs someone to keep him company Spells Boundless Enthusiasm, Lets you move maxx if u need to but generally is good in a ton of situations definitely worth the include. Fiery Ambush. Points and laughs at your opponent while you guys are fighting for a font Mandate of sheoul, 25 hp heal big damage buff. It hurts Masochism, See Nefari Guardian Mindslicer Boomerang, It hurts A LOT for a low low price of 35 nora Mindstorm, it also hurts a lot Rapid Assault, awesome synergy with dark summons but in general a big tempo buff and if you use it on a high cost champion it costs Bane Shift all thanks to equalize. Also cause of this decks focus on relocation it can get a champion from a deploy zone to front line really quickly and put your opponent on the back foot. Retribution. IT HURTS A LOT. also 3 perserance units you'll get plenty of chances to use this efficiently. pretty much a guaranteed kill which when you have maxxarek out can do a ton of damage Sacrifice, Great for trading units with your opponent and constantly sustaining an assault or even making a stand defensively Just a warbanner. im not going to bother explaining this you all get it 2 demon shields. Keeps maxxarek safe from 5+range poking
