Alexwkd08 try reducing to 1 titan instead of 2, i reccoment the Fire titan. But then make the rest of your units this, Dragon Rider, Mermaids, Succubus, Archers, Phantom Armor or a unit of your choice.
Then when it starts just rush and when he sends out the 2 titans at once just fall back use Athena Protection and Zeus Wrath, then by this time all your units titans should be there and then just own them! :)
