Me thinking the broken strategy for this week is.
Duke 1 corner.
King/Queen other side.
E-Dragons centre.
Revive or recall the dude.
Force close the game.
The Dragon Duke will be MAXED for the first week based on your TH level. This includes the Equipment in which there are 3 Common Equipment at first. There will be an Epic Equipment for it in April.
The Dragon Duke has a Royal Rampage ability when it is at least 6 tiles away from other air units, so you want to try and utilise that in your attacks. I would recommend the Flame Heart and Flame Blower for this. The Dragon Duke is a high HP melee style unit so you can just merge it with Dragon attacks as it'll tank for them. You could even solo an area of the base, then Recall to send in with Dragons. Check out my YouTube video for a full breakdown of the New Hero and let me know how you plan to use it!
