So, the deck became a lot more consistent with the new support. This is currently what I've been working with, limiting to just the cards I have IRL plus the new cards. It's super recursive, but needs to be able to search wave (which we either have another link monster or main deck monster that hasn't been revealed yet, so there is still hope.
The new link 4 outshines all of the other link 4's by both being removal and negation (however only removal on your turn and negation on the opponents). Hopefully this can be a good starting point for anyone who wants to try the deck out!
