I love playing this Echo Makto deck. I used primal (blue) instead of fire (red) adding drawing cards like trailblaze and wisdom of the elders to speed up your game.
The main play is to give echo on your revenge minions and when you redraw a revenge minion w/ echo it will duplicate a copy.
Aggresive decks are the main problem, survive using lifesteal from your Piercing Grief and Alchemist.
Your biggest minion problems are Steward and Maiden and also silence cards, i use feeding time instead of deathstrike or banish so that your opponent cannot revive these two annoying minions in their void.
I have add 2 Trailblaze for Seek Power and i am not having any problems with mana. Only issue is the two Primal for Wisdom, so thinking on changing the thrid one for a third Trailblaze.
Also added the Crest i currenty have ( 2x Crest of Cuning and 1x Crest of Vengeance) and change some Seats.
Current Mana: 2 Time, 4 Justice, 2 Primal,4 Shadow, 2 Seat of Progress, 2 seat of Order, 1 Crest Vengeance, 2 seat VEngeance, 2 Crest Cunning, 2Seat Cunning, 2 Seat Mystery)
I dont have maktos so I run Watchwing consript (works really well with the deck).
I am also testing wanted poster in this deck instead of devour. Seems easier with tons of removal to draw cards, then to have a unit to sacrfice.
For power fixing, yeah it is a problem this type of deck always has, but if you highly prioritize 4 power hands in mulligans and then create your gameplan around the colors you have, it's not too bad. For example, I just played a game where I had no green in my hand after a redraw. I did however have a piercing grief, 2 dark returns, and a strategize. I strategized away green cards like harsh rule, while focusing my gameplan around swarming them with increasingly large piercing griefs and won.
Watchwing is a goodsubstitute for Makto if you dont have him, but the UNLIMITED revenge + echo of Makto makes it a winning condition.
I think wanted poster is ok but what i like with devour is a fast spell w/c you can use if your opponent kills one of your minions and also lifegain
