Once again, I turn to you for your wisdom:)

Why this works:
-----------------------------------------
class Depo
attr_accessor :test

def initialize(test)
@test = test
end

  def test()
  @test
  end
end

bla = Depo.new("blahdsd")

def defin (bla)
if defined? test
puts "#{bla.test}"
end
end

defin(bla)
------------------------------------------

And this doesn't:
------------------------------------------
def effect_output(card)
  if defined? attack
    puts "#{card.name.capitalize} hits with #{card.attack}."
  elsif defined? heal
    puts "#{card.name.capitalize} heals for #{card.heal}."
  end
end
------------------------------------------
The card is a DRAGON class object with method attack defined. It has the 
attr_accessor as well as initialize method defined. I don't even get an 
error. Nothing gets putsed.

If I use

if defined? :attack

then I get the message that attack is an undefined method for class 
HEAL.
