This is my ChaosGallantmon deck. This is not a Megidramon list but it does use some cards from them. The main benefits to running ChaosGallantmon are simple actually. You get to keep your field while still having the same on deletion rush down strategy. You can delete your own stacks to unsuspend and play more stuff back from trash which in turn lets you attack more often. You then pair this with MedievalGallantmon and Gallantmon Crimson Mode Ace to help finish off your opponent and control the board. This deck is neat but it isn't as strong as Megidramon is as of this moment.
