This is my updated Xros Heart deck. It is much more refined than it previously was since I have been doing extensive testing for it. It uses the Luminamon and Sparrowmon engines to help get to its pieces while setting up or clearing stuff off the field. Meteor Rock Soul is now maxed out since it is a key card for a lot of the decks combos while also being important for looping your Luminamon and Shoutmon. Also since Luminamon is a Xros Heart that's a level 5, it can evolve into Shoutmon DX. So if they stick around they can be used to clear a body off the field and do two checks. If cleared off the field you can then use Save to put them underneath one of your tamers which in turn lets you replay them back out with Meteor Rock Soul to use the on play again. Meteor Rock Soul can also be used to unsuspend your EX6 but you won't be needing that effect often. It's mainly in here for its first effect. The tamer lineup was chosen to help you digi-Xros and cycle through your deck. You can also use the BT 21 Taiki to let you attack when you pass turn. That is extremely important for the deck. You can hard play a Shoutmon King Version to play them out while using Digi-Xros to have a Shoutmon underneath it. It gains rush and can immediately attack using the tamer and this is all for only three memory. The more I tested the deck the more I realized just how strong these cards are. I've posted other builds before but this one is probably the strongest out of all of them. But maybe that's just the way I play the deck.
