Jaffa Ball uhhh oops, heh heh. I forgot the OP got updated not terribly long ago and removed HP ice from the first set, for some reason TC doesn't like HP ice. I'm not sure if I like lando-I as a lead though, because he is actually pretty frail and a strong neutral hit from a faster mon (which there are plenty) means that you have just lost your best wall breaker. SR is used sometimes because lando-I has such good 3 move coverage that he can set up hazards on a predicted swap if lando can't simply bust down the swap in for whatever reason.
Vengeance417 I used to, but it only really works if you have other fast, hard hitting mons that can take advantage of the momentum. Lando-I is kinda like genesect in that he forces a lot of switches, so if you pair him with terrakion or something, you might get some work done.
Swami I dislike trying to use lando-I to take on chansey. Knocking off eviolite is great, but you still need to hit two consecutive focus blasts to kill it off, otherwise it just PP stalls with softboiled. I don't like banking on hitting 2 focus blasts unless I have gravity up.
