Imotekh B artifacts deck help

Been working on an [[Imotekh]] deck for a while and finally got something that consistently churns out tokens. Thinking the deck has gotten fairly fast and is fun to pilot. I think the deck needs some help with resilience and game ending. Either something to help the tokens get the kill or other combo lines that work with the deck. Also worried the deck shuts down whenever the commander isn’t online, so having an alternate goal to still be able to work towards is good. Lmk what y’all think. All suggestions are appreciated.
