SM Combat Trials Test

This challenge pack consists of the first 3 stages in what I want to call "The Scrap Mechanic Combat Trials", a series of portal/master mechanic trials styled chambers of challenges meant to improve players combat tech in-game. I have released the first 3 stages to get opinions on the concept and see if there is any interest before I keep making more of these. Also balancing. Do note these first 3 are the melee trials, later trials will use the spud weapons and other niche mechanics or gimmicks to add variety to the game-play. Please leave any criticism, ideas and opinions in the comments. (Side-note, i noticed you can block in challenge mode but it does not work. It's just the animation for it, you still take the same damage. This only exists in creative and challenge but has been removed from survival)
