What will change if there is a battle of 7 Fairies against 7 Behemoths? I'm not against it – create maps, and players will base their decisions on what they see on the battlefield and what they have at their disposal.
Ultimately, 7 Fairies against 1 Behemoth is already enough to "get the idea." And there's no need for automatons, "cheaters," or other gimmicks.
-- Julius Caesar, 47 BC
