Here is my personal Nekroz/Ice barrier deck,
I started playing nekroz but I found that they were too weak against this meta (and because it's a ritual archetype) and I wanted to try something different of the classic Nekroz/Dogmatica so I searched for another deck to use as an "engine" and that can have some interractions with nekroz cards, and I picked up "Ice barrier" for that (because I love synchros)
Now I find the deck a little more decent but it still weak against competitive/meta decks (but it's not impossible to win)
I will try to upgrade it when I can to make I work better, try it if you want and help me with your comments, ENJOY ^^
