i added my deck to Nikachu's deck review discord channel and he checked it out. he made some good suggestions and i decided to enact on them.
first lets talk about the cards we removed, then what new cards we added, then what cards we added more copies of, then finally the suggestions i wont be taking from nikachu.
we removed mercy killing, dress down, brass city, swamp, and idyllic tutor.
Nikachu made some good comments about how mercy killing was not really doing much as a 1 of, as well as idyllic tutor. dress down was also not doing so well in this deck anyways. i made the decision to replace brass city with a strictly better card. the main reason is because when you tap brass city you will take damage, no matter what sort of enchantment you put on it (well except spreading seas but that is for our opponent).
the cards i added to the deck are:
The Meathook Massacre, and mana confluence. Nikachu's chat made the suggestion for the meathook and he agrees it would be an amazing card in this deck. it is removal which this deck needs and it is a good plan if we can't find our combo peices or if the opponent has removed our stax peices that are keeping creatures at bay. i made the decision to replace brass city with mana confluence mainly because it does what brass city does and if we add an abundant growth onto it, it wont damage us when we tap for mana; unlike brass city.
we also added more copies of:
field of ruin, and sphere of safety. i decided to take out the swamp and replace it for a field of ruin, mainly because we dont use a lot of black mana. i added 1 more copy of sphere of safety because i thought it would be better in the long game for our deck.
the suggestions we wont be taking from Nikachu:
we are NOT going to remove Avatar of Might. Nikachu really didnt see the value of Avatar of Might in this deck, mainly because he had the assumption that we would be giving our opponent so many creatures they would die to blockers. he thought a good idea would be to remove Avatar of Might entirely to add more copies of hunted phantasm or other things. he also made the assumption that this deck wins more with trespasser's curse. the facts from playing with this deck alot is that the deck wins more with Avatar of Might than it wins with Tresspasser's curse. the soonest we can get an Avatar of might on the field is by turn 3, by having 2 forbidden orchids. once we have the avatar out, we dont need to give our opponent any more creatures. while some say that it would make it that we cant tap our forbidden orchids for mana anymore, all you have to do is swing in with the avatar of might. by then if you have been playing optimally, it is a 8/8 trample against their 4 1/1s. and if they dont block, we just play more of our stacky stuff and keep swinging eachturn till they are dead or we can drain them out with the trespasser's curse or burn them with the rakdos charm.
if we removed the avatar of might, then why play forbidden orchid or tresspasser's curse? why not just make it a regular stax/ enchantress deck? this deck is called Chromatic Stacky Avatar for a reason and Avatar of Might is not a deadweight to this deck.
now, if you really wanna remove Avatar of Might, i would recommend replacing it with Suture priest. this is basically a trespasser's curse on a creature and will help you burn the opponent out even more.
