Now working with this lando variant in the new November 8th rules, I found that some of the older less played cards like cheren, Bianca, etc to be very helpful. I have always liked at least 1 cheren in lando because half the time you don't want to shuffle you're hand into you're deck and you just need that extra 2-3 cards even if it takes the supporter turn, then again this is only 3-4 weeks in to testing so idk, time will tell from tournaments, etc.
