Meta viable build of Vaylantz
When playing the deck I have been able to consistently beat labrynth and vanquish souls and consistently takes games/ almost beat kashtira before the banlist with the new banlist in action it should be able to beat kashtira more often.
The boards you make are only breakable by dark ruler no more kaijus and lava golem don't work with fossil dyna being on the field.
I've found I:P avramax this format is very effective as not many decks have cards that can out it.
