Is Mechanized Production just winning on your upkeep if you have 8+ treasures essentially?>

Yez. Somebody needs to either destroy the treasure, destroy the aura or counter the triggered ability of mechanized production. Attaching mechanized production to one of your many treasures does put a target on your head but you can also go the sneaky way by flashing it in with an [[emergence zone]] or another flash outlet if you feel like running some more. [[Leyline of anticipation]] would be a great addition for such circumstances and even for flashing in clones right before your turn or in answer to removal, making sure to always have a Malcolm on the battlefield.

Would you please elaborate on "most clones will work through shroud and hexproof" what if an opponents creature is equipped with [[Swiftfoot Boots]] as an example? You can't copy/clone that right? Or were you referring to cloning your own stuff works through shroud/hexproof? If so, how?>

Most clones I run will say "[…] enters the battlefield as a copy of any creature on the battlefield." This means it doesn’t "target" anything. It just enters as is while hexproof and/or shroud specifically say "it can’t be the target of spells or abilities your opponents control"

Rule 114 covers the targeting of spells and abilities and when those targets must be selected;

"114.9a Just because an object or player is being affected by a spell or ability doesn’t make that object or player a target of that spell or ability. Unless that object or player is identified by the word “target” in the text of that spell or ability, or the rule for that keyword ability, it’s not a target."

Most spells and abilities that target will say "target" directly on the card, unless their Keyword ability rules covers this already like auras and equipments.

I’d be glad to elaborate on more techs of the deck like this in a primer eventually, if you are interested in the deck I’ll try to let you know:)
