This originated as an aggro hate deck (all lifesteal units, 4x defiance) when I kept encountering rakano at the start of the season. While playing other Chains decks I realized you can give anything a late game by main decking a bunch of chains. Wingbrewers were added because I wanted more card draw than just Fenris and the Oathbreaker/Vampire Bat synergy is just a nice little bonus. Plug in some Vanquisher's Blades or a market Gavel if you're in need of void hate.
Like any Paladin deck the ideal opener is turn 2
Anointer of the Faithful, turn 3 bond an expensive paladin to
Hojan, Crownbreaker.
Copperhall Paladin is great in this scenario but is quite weak without anointers on the field.
Wingbrewer is generally played as a 5 drop and Vara's Favor is your Hojan activator if you don't have any Anointers.
