Numerical conditional within tikz keys?

I would like to set up a presentation in which different parts of the same tikz picture appear, depending on the value of one, perhaps more, integer variables. I tried at first using a fixed picture, with changing the visibility of the different path elements of it, depending on the slide number, but this did not scale. There are about 150 slides in a single frame.

Then, I tried an alternative in which the entire picture is defined as a macro, which is invoked once per slide, with different portions showing based on global conditions. However, I failed in including conditionals within the keys.

Here is a not so minimal and certainly not working example demonstrating my failures. Any help would be appreciated:

documentclass{beamer}
usepackage{tikz}
usetikzlibrary{chains}

        tikzset{%
            invisible/.style={opacity=0},
        }

newcounter{count}


newcommandmyPicture{
begin{tikzpicture}
  begin{scope}[start chain = going right]
      node[draw, circle, on chain] {
      ifnum value{count} > 1
      {Count is greater than s}
      fi};
  node[draw, circle, on chain,opacity=0] {B};
  node[draw, circle, on chain,  ifnum value{count} > 1relax invisiblefi] {C};
    node[draw, circle, on chain] {D};
  end{scope}
end{tikzpicture}
}

begin{document}


begin{frame}
setcounter{count}{2}
ifnum value{count} > 1
{Count is greater than 1}
fi
ifnum value{count} > 2
{Count is greater than s}
fi



only{
setcounter{count}{2}
myPicture
}

only{
setcounter{count}{1}
myPicture
}
only{
setcounter{count}{2}
myPicture
}
end{frame}
end{document}

Here is a minimal example giving an idea of the expected result, but of course, without achieving it:

documentclass{beamer}
usepackage{tikz}
usetikzlibrary{chains}
newcounter{count}
newcommandmyPicture{
begin{tikzpicture}
  begin{scope}[start chain = going below]
      node[draw, rectangle, on chain] {display only when counter is between 1 and 3};
  node[draw, rectangle, on chain] {display only when counter is negative}; %
  node[draw, rectangle, on chain] {display only if counter is between 100 and 200};
  node[draw, circle, on chain] {only when counter is in the range 3 to 20};
  end{scope}
end{tikzpicture}
}

begin{document}
begin{frame}
only{setcounter{count}{-3}myPicture}
only{setcounter{count}{105}myPicture}
only{setcounter{count}{39}myPicture}
only{setcounter{count}{2}myPicture}
end{frame}
end{document}

  ifnumvalue{count}<1 expandafterGobToSemiColonfi
  ifnumvalue{count}>3 expandafterGobToSemiColonfi
  node[draw, rectangle, on chain] {display only when counter is between
    1 and 3};

  ifnumvalue{count}>-1 expandafterGobToSemiColonfi
  node[draw, rectangle, on chain] {display only when counter is
    negative}; 

  ifnumvalue{count}<100 expandafterGobToSemiColonfi
  ifnumvalue{count}>200 expandafterGobToSemiColonfi  
  node[draw, rectangle, on chain] {display only if counter is between
