When I read this article about an Autocast Paladin build. I thought that it was too impractical for commoners, since that build required 3 Boss cards and extremely rare Valkyrie items to be effective.

However, let me share with you my autocast build using equipments which most people can afford:

Weapon:
  Fireblend / Ice Falchion
Shield:
  High Orc for PVM or Racial Card
Armor:
  Pest, Loli Ruri
Accessory:
  Wind Ghost, Bongun, Violy, or Owl Duke + Owl Baron (be careful of Lex delay though)

The basic principle of an autocast paladin is that you use the inherent ability of reflect damage to auto cast. This build only requires that you have a high INT. All the other stats will depend on how you want to play your Paladin (if you want to tank, pump VIT, if you want ASPD, pump AGI). In WOE, pest and violy is quite a good combination in breaking precasts, especially when the enemy guild is GR infested.

However, due to the recent updates on RO, the autocast Paladin became quite impractial since the autocast chance was nerfed =(

It was good times before that though, here is my autocast Paladin in action:
