Abstract: Together with Alexander Tsymbaliuk, we propose a blueprint for constructing shuffle realizations of various quantum loop (super)algebras; this is a valuable tool for the study of these important algebraic structures and their representation theory. We apply this framework to the case of classical super-types A,B,C,D, which leads us into new combinatorics: higher order wheel conditions on one hand, and on the other hand certain generalizations of Young diagrams that we call shrubs (in types A) and asps (in types B,C,D).
