I don't get what you mean op do you wanna learn how to play shaco? He isn't easy to abuse like YI, Jax, or XIn so you'll have to practice quite a bit before being able to be effective in ranked.
for runes I usually go ad reds, flat MR blues, flat armor yellows, attack speed quints. So a standard build.
Masteries I take the regular thunderlords path since I rely heavily on burst damage to burst squishies down since shaco is shit at 1v1 due to being made of paper.
Also please for the love of god practice him in normals for about 40 to 60 games before going to ranked.
It takes time to learn all his tricks and counterplay mechanics so don't just learn the basics and rush in because unless the enemy team has never seen a shaco you are going to lose a lot of games since shaco falls behind hard if he's countered in the slightest early on.
Tl:dr Practice. Shaco isn't a free win champion like Yi and will take a lot of knowledge to be able to do well with him
