You know that scene in the Lord of the Rings where those massive elephant-creatures storm into battle with a whole host of troops on the back? Yeah, except for an order of scale, that sort of thing did happen. War elephants were essentially the tanks of their day. The creatures were very resilient and could carry platforms on which troops could use long pikes or bows and arrows to attack the enemy. Now they can come to your Hail Caesar tables, too.
The armies of Alexander The Great encountered these beasts and incorporated them into their forces. Various generals would go on to have great success with them, including the Seleucids, who used elephants so effectively during an attempted invasion by the Galatians that a route ensued, the battle being remembered as The Elephant Victory. Maybe they can bring you victory on the table as well.
