Let me just start by saying Eternity Code and Master Rule 5 excites me more than a 5 year old in a toy store. Dusting off the ol' Dinosaur deck ready for April 1st, I've been playing around with different strategies for the deck. An example of this is the new Jewel Beast - Argosaurus. That bad boy is a 1.5 card combo to end on a Linkuriboh, a Rank 4 of your choosing, and either an Ultimate Conductor Tyranno OR Overtex Qoatlus. However, the main combo for this deck involves Ultimaya Tzolkin. Sounds insane right? But thanks to Master Rule 5, it is not only possible, it is the nuts. Ending on a board of Apollousa, a Level 7/8 Dragon Synchro, and either Ultimate Conductor Tyranno OR Overtex Qoatlus is nothing to laugh at. You can further extend this with a Naturia Beast if you have access to Giant Rex. Would I consider this Meta-Breaking? No. But it sure can be difficult for most decks to get around with the buff to Dimensional Barrier.
I will be happy to explain how this combo works if people ask for it.
