I'll try to be more original than lati+something, so here's lurerachi+something. In all seriousness, lure rachi is pretty sick as it lures and kills pretty much most phys walls like lando's and slowbro's while also having lasting support in healing wish. So pretty cool combo of luring the thing that walls your attacker and healing wishing that attacker after it gets worn down. I chose Lop bc I've been using it a bit recently and it gets walled by bro and lando and skarm, but really you can use pretty much any threatening physical attacker that gets walled by one of the many mons jirachi jures, such as Pinsir and Lucario.
