I think I've finally settled on my 4f makto deck for dusk road. Not much has changed but the new crest cards are absolutely amazing for the deck. Scout has a special synergy with revenge as moving closer towards your revenge units :)
I think where other Echo Revenge decks fail and this one succeeds is because this one is committed to splashing the colors outside of argenport. TJPS variants of the deck for example are good at times but the fact that they are full primal instead of splash fire makes your deck severely less consistent, besides primal mostly just adds card draw and we have 10 draw cards.
Torch,
Purify,
Banish, and
Vara's Choice are all good cards but if you rely to heavily on your non main faction cards you can get totally bunk openers. The key to playing 4 factions in one deck is balance. We don't get the bread and butter of fire and time, their place in our deck is to facilitate our combo. Keep removal to Argenport because you will always have the influence requirements and argenport has the strongest removal in the game anyway!
