Help on the internet can only go so far. Some spellbooks can look great on paper but fall apart it battle. Others might look boring or "not that great" on paper but still be devastating in action. The best advice is to keep playing with your spellbook. When you play a match, think about what cards you aren't using, what cards you wish you have included, what cards you think you have too many of, etc.
Overall, with any spellbook, I aim to achieve two goals: 1) Play to my Strengths; 2) Cover my Weaknesses. The Warlord's strengths are his speed and his creatures. The Warlord's weaknesses are probably his inadequacy when it comes to dealing with anything "arcane." When you make a Warlord spellbook, have a fast aggressive strategy in mind, but don't neglect your weaknesses. I kinda like how you threw in some non-earth attack spells in your spellbook. One weakness the Warlord has is his predictable emphasis on creatures (a weakness shared by the Beastmaster as well). By throwing in some attack spells, you may be able to throw your opponent off guard.
