Shapeshifting cubes Help?

[panzerhacker]

Ive been trying to get into other types of cubes like shapeshifters and basic cuboids, can anyone suggest some good puzzles to start off with these types of puzzles?

3x3x4, and axel cube. both real fun and relatively easy to wrap your head around when starting out cuboids/shape shifters

This, plus the fact that it's an official event and you can actually compete in it.
