The best way is to position guards with Intercept in the same area.  Of course, one reason to have four is to make it so that you have replacements.  In general, howver, it is the teleport murder that is the major problem (Royal Archer shoots Beastmaster, Beastmaster teleport Royal Archer into pack of Dire Wolves, Dire Wolves eat Royal Archer), though there are now spells with Anchor.

 Of course, the best murder squad is Brogan Bloodstone supported by two Knights of Westlock and two Guardian Angels.  When that hits the field, it is pretty much game over, as 14 dice of damage, which can stop two attacks per turn, is hunting down everything on the field.

Ah, I understand.  I have found that I need a deep roster for maximum flexibility (though I will admit that I have not been getting much use out of the Royal Archers lately).  Now, with the Siren vs Paladin set, I may end up changing my book, as the diversity of new creatures may be better at creating the flexibility that I desire.  The Knight of the Red Helm, for example, seems to be quite promising.

I generally bring out a Guardian Angel and Mana Crystal turn 1, a Guardian Angel and Mana Crystal turn 2, and a Moonglow Amulet and a Harmonize turn 3.  After that, I pop out Knight of Westlock or Royal Archer every even turn and use the odd turns for attack spells or healing spells.  I generally take 20 points of damage by turn 7, but I can generally be back up to full life by turn 9.  By turn 11, I generally win (around 3/4 of the time), though I have problems dealing with Straywood Beastmaster (Warlords and Warlocks tend to die by turn 9, Druids and Necromancer tend to die at turn 11, while Forcemasters and Wizards tend to die by turn 13).  Of course, I have only played around 500 games, so it could just be lack of experience.

The female warlock is actually a little weaker than the male warlock because she has to be more strategic in her choices.  A male warlock can summon a bodyguard before going out to deal damage through melee.  The female warlock needs to be more judicious and barbecue her foes from a distance.

I agree, which is why I have learned to not use my spawnpoint unless it is defended or the opposing mage already on the defensive.  The Druid's Tree is actually more important than other spawnpoints though, because her very life is impacted by its existence.  Of course, it is very tempting to use the Druid's Tree, but it is necessary to be strategic as well as tactical.
 

You are playing with a more polite crowd than I am if you are able to keep your tree alive longer than the third turn.  Our group tends to turn the spawnpoints into rubble by the third turn, so I have learned to avoid depending on it early game.  Since Druids do not have an easy interceptor (Gargoyles or Guardian Angels are six spell points each), I just wait to cast my tree until I need to additional life recovery.  Otherwise, it will just be turned into kindling before I get my mana out of it.

I really do not see how this build would deal with a Beastmaster, a Priestess, a Necromancer or a Wizard because of the swarming.  I also do not see how it helps against a Druid (who can melt your equipment off of your flesh), a Forcemaster (who can mind control your creatures) or a Wizard (who can deal massive spell damage).  I do not even see how it works against another Warlock because, after they get rid of your Armor, they will just barbecue you.  Please tell us how it works out for you because it is a counterintuitive build.
