A THREAD FOR NEWCOMERS!

Basically, my friend and I will be finishing a game tomorrow, and I don't know how to win against him!!!!!) So, here's the situation:

Me: 1. Inferno, all buildings are fully upgraded, even the Devils.
2. Another Castle, a Tower, where the fleet hasn't even been built.
3. No army, because I attacked him at his main Castle.
4. I have a Portal of Dimensions, Expert Logistics, Chain Lightning (285 damage), 40,000 gold, and a lot of resources.
5. My hero's skills are 3, 8, 8, 6.

Him: 1. Swamp, main hero with 4, 12, 4, 4. A strong army, like 5 Hydras and the rest around 50 each....
2. He probably has another Castle, but I don't know what it is.

So, that's it! I don't know how to use my strengths in logistics, money, resources, the Portal of Dimensions, and Chain Lightning!

The map is large, about 70% of it is land, and most of it hasn't been captured yet
