>>32243674With Eviolite you could try to use it as a Cleric/Support I guess. Aromatherapy, Synthesis, then your choice of moves. There's dual screens, leech seed, sub, protect, thunder wave, baton pass, toxic, grass whistle and stuff.
You could either take advantage of its speed and boost that and hp, or if you can give it sun support, go full defensive nature+EVs while still being somewhat fast thanks to Chlorophyll. You probably want an attacking move so it isn't Taunt bait, maybe Double-Edge to try to make up for the low attack stat.
For LC, just go check the smogon sets for XY.
