Walkthroughs for custom maps.

What are some ideas for breaking through an anti-magic dragon garrison? Our units have higher speed. We can use any units within the available budget. We could take 50 bears or 70 hydras with the "Titan's Roar" skill. The save file is attached. You can delete units – for example, I tried adding single griffins. You can also give griffins or knights a "regeneration" buff. The goal is to minimize losses of archers, snipers, wizards, monsters, and hydras. We can probably afford to lose around 40-60 champions as well.
