So you main urgot yes? If not, you should. Urgot at the moment is a very tough ADC when caityln isnt outranging you. Combine yourself with an ornn or other aggressive support and you will be wining the early and mid game.

Q, your poke. You must max this first but 2 levels into it.then at level 4,7,and 8.
W, your shield. This needs to be leveled up after your q. Lvl 3 is optimal to help prevent the main combos of other adcs. It gives ghost effects over minions and provides a shield for %hp making black cleaver a good item with steraks.
E, stun. Utility skill to hold another carry or a support in place for you to deal true damade and proc press the attack
R, calcuemulated skill shot. If the carry or support is running with the hp under 25% landing r will enable you to execute. If braum blocks the rerurn he will be grabbed instead and can die at full HP. R also allows you to gain free kills when roaming mid or top as your teams hard work might be wasted by a recall ;P you are welcome whining midlaner
