K I did ctrl+f Lickylicky in the first page and found nothing, so here goes.
I was wondering whether it was getting analysis or not. It's got pretty good stats all around, with 110/95/95 defensive stats and 85/80/50 offensive stats. Additionally, it's got a very colourful movepool, and what sets it away from other Wish passers like Alomomola is access to Heal Bell. It's also got access to wonderful offensive moves with stuff like Fire Blast (Fire Punch), Thunderbolt, Body Slam, Knock Off, Dragon Tail, and even niche things like Counter that can be surprising. Now, some obligatory calcs:
(calcs mostly for spdef lickilicky but phys def is also viable.)

etc. etc. It seems pretty viable to me with the reasons I stated above, and its able to take hits from the hardest hitters in RU really well based on the calcs I ran.
also, credits to thinking of writing lickilicky go to Sapphire. ~
edit: I also feel obliged to talk about its faults too, and not only the colourful side. I'm going to start with its normal typing; it doesn't give it any resistances at all, an immunity to Ghost, and a weakness to Fighting-types, which means it doesn't like Hitmonlee, one of the most common spinners/wallbreakers in RU. It's got okay-ish attacking stats, but its kinda too slow and its offensive presence isn't exactly high. It also suffers from 4MSS a bit; wants to run all of wish/protect/body slam/heal bell/fire blast/knock off/dragon tail but can't, and has to settle with four of them only.
