OK 2, electric booglaoo
I've been pondering what you could take out of your deck and essentially it boild down to
1. WINMORE (Cards that are technically good, but you dont need)
In this deck and in my opinion, your top end should be
Triplicate Titan and
Phyrexian Triniform. Maybe Blightsteel Collossus since it kind of has recursion so you could sacrifice it as often as you can get it out. Maybe more on that later.
So in you place I would take out:
Platinum Emperion (big do-nothing, no payoff for your strat)
Maelstrom Colossus (cool but the very definition of Winmore)
Darksteel Sentinel (Expensive for very little payoff)
Mycosynth Golem (Also cool, buuut...)
Golem Foundry (It only works on CASTing an artifact - the gingerbreadmen wont trigger it. As sad as it is, dont waste a slot on this, its too slow here.)
Splicer's Skill (cool and on theme but not really worth it. Its essentially just a 3/3 vanilla golem)
Leyline of Anticipation (No.)
2. DEFENSE
I understand why you have a lot of defensive things in here - your deck felt slow and you wanted to protect your stuff until it got going. With the changes and suggestions from this and previous comments however, I think you can cut back on it a bit.
Padeem, Consul of Innovation OR
Oak Street Innkeeper (I recommend to only keep one)
lose one or two counter spells - Disdaiful stroke?
Stifle?
3.Other
Winds of Abandon? Not sure about this one. Exiling automatically makes its so your commander doesnt work if oyu have to use this. Maybe try
Organic ExtinctionSInce I've already made a suggestion, Ill move on to the last part.
SUGGESTIONS
(cards to put in)
Organic ExtinctionSecond Harvest Symmetry Matrix Eternal Scourge (not a golem, but really cool tech here)
I also realized you definetly need more ways to sacrifice your creatures so you can use your commander!
Stuff like
Ashnod's Altar (!)
Culling Dais Birthing Pod (expensive :\)
Witch's Oven (on theme
)
Pyre of Heroes Alright! So far so good.
Keep in mind that all these suggestions are based on my immediate knowledge and superficial research. Youre gonna have to do the deep-dive yourself
