\tikzsetstuff is precisely that you do not have to carry it around. You could (at least) simplify your command to\newcommand{\yourcmd}[4]{% \scalebox{#1}{\begin{tikzpicture}[font=\Large,scale=1] \LifeWeel[#2]{#3}{#4}\end{tikzpicture}} }and say\tikzset{life wheel/.cd, ...}only once. – Mar 23 '19 at 15:36
