The best thing to do in any match is to build your two or in some cases one primary building which are the basic unit buildings that make your swords man,archers,and pikemen. In every match mode you start off with two builders use both to make the buildings and with (or if there's enough) make a hero and send out the hero and two sword battlions and an archer battalion after those building are made you should really focus on resources. While your first attack squad is attacking the base you should be making a follow up attack squad and you should be in control for the rest of the battle.
When playing as Mordor, remember that they aren't a good race to be defensive with. If you play defensively, you will most likely lose.When starting out, have one builder create an Orc Pit and have the other build a Slaughterhouse (which should be shooting for above 80%).
However, Mordor excels at offense (their Attack Trolls and siege artillery are capable of levelling a fortress in seconds). Mordor's power lies in its numbers.
This is an effective building order that I use myself in most of my matches.
When your Orc Pit is complete, construct another Orc Pit. Consecutively start training Orcs. It is imperative that you build lots of them; queue up at least 5.
The builder who built the Slaughterhouse should now build another Slaughterhouse.
Have the Orc Pit builder construct a Troll Cage.
You should have at least 3 Orc battalions by now (you've probably noticed that they build very quickly). Select all of your Orcs, and move them to your opponent's base.
PROTIP: DON'T FORGET YOUR POWERS. PURCHASE "TAINTED LAND" TO GIVE YOUR ARMIES IN ITS RANGE A +50% ATTACK AND DEFENSE BONUS.
When you get there, ignore his units. Head straight for his structures. Taking out his unit-producing buildings (Archery Range, Barracks, Green Pasture etc) would be great, but you can settle for the resource-producting buildings (Slaughterhouse, Mallorn Tree, Furnace etc). Set your Orcs' battle positions to Agressive, which heightens their attack but lowers their defence, and have all of them attack a single structure.
Once its destroyed (remember to ignore your opponents' units), scout around with them until you find another structure, and attack it, but your Orcs are probably dead by now. Which isn't a problem what-so-ever, because the other Orcs will now have arrived and can attack the structure. Try using Tainted Land + the Agressive battle position to destroy it.
While you're doing this, you should also be concentrating on your base; building new structures and tightening your defenses (now would be a good time to upgrade your Troll Cage; the sooner you can start creating Attack Trolls the better).
By using this strategy you have forced the opponent to go on the defensive trying to defend his base, and you've also damaged his economy by forcing him to rebuild lost structures.
Stay on the offensive unless:
He has cavalry. Construct a Harradrim Palace and produce Easterlings, which are pikemen.
He has lots of archers. Train some Mountain Trolls to destroy them.
He has pikemen. Produce some archers to deal with them.
Also, while this is happening, don't neglect your base, or your heroes. Picking heroes and powers is dependant on the map and your opponent.
As previously stated, when using Mordor the main thing to remember is to remain on the offensive at all times.

Celebrim - Win 10 resource race games
Ohta - Win 10 versus games.
To easily level up heroes, find a wild goblin cave, a warg den, etc.
Put your hero on Defense Mode, and let him attack the people surrounding the den. He/ she won't attack the den, instead, he'll wait for more wild enemies to come out.
This is a great way to level up heroes quickly.
Win 10 vs Matches, then you get the greatest hero....Ohta. He has Cripple Shot against heros, Elendil in case you need to escape, Whirlwind to take out HUGE armies in a small amount of time, and Arrow Shower, which takes out huge armies in almost no time at all.
Once he's level 10, he's unstoppable.
