@10XL my new code with struct instead class. It has passed all tests.

require 'nokogiri'
require 'open-uri'

class LeaderboardArray < Array
  def size
    length-1
  end
end

class Leaderboard
  def self.build
    Struct.new('Warrior', :name, :clan, :honor)
    @@leaderboard = LeaderboardArray.new

      url = 'https://www.codewars.com/users/leaderboard'
      page = Nokogiri::HTML(open(url))
      rows = page.css("[class='leaderboard pan'] > table > tr")

        rows.each do |row|
          name, clan, honor = row.css('a').text, row.css('td[3]').text, row.css('td[4]').text.to_i
          @@leaderboard << Struct::Warrior.new(name, clan, honor)
        end

    @@leaderboard

  def self.position
    @@leaderboard ||= self.build
