Hey! I prefer ludens in basically every matchup in support. Preference here is that you save up the ludens proc and use it for a hefty trade while getting movement speed to kite away. Also Dark Harvest can be good but its less effective in support because it takes a decent amount of poke to get people low. Comet is generally good for larger trades so you can poke the enemy out of lane while saving q to disengage if they posture forward. Once a health lead is established you can look to use your q more aggressively for engage/kill potential. Crown could work but I prefer positioning behind my carries and really getting zhonyas if necessary for survival. You lose a lot of damage with crown which is usually why you see it mid lane vs assassins as mid lane lux scales faster than support so your damage is still relevant.
