The thing about Landorus-T is that it has checks that don't overlap with Keldeo's (and in many cases aren't Pursuit weak), preventing CBTar from fucking over a team quite as easily. Skarmory is an excellent check to both Landorus-T and CBTar, and takes a huge chunk out of Keldeo should it try to switch in. Landorus-T is actually a check to itself, assuming neither carries HP Ice. Heck, if Lando-T isn't running a special coverage move, Poison Heal Breloom can take it out, and Keldeo loves switching in on Breloom.Predictably Landorus-T replaced Landorus-I in the popular Keldeo/Tyranitar/Landorus core.
And it performs virtually the same way. I don't think banning Landorus-I accomplished anything.
