I've also tried something with until:
-------------------------------------------------------------------
begin
  possible_cards.each do |name, type|
    if type == "dragon"
    deck_dragons << name
    end
  end
end until deck_dragons.length.to_i == @dragons_qty.to_i
-------------------------------------------------------------------
... but it doesn't work either
