Winners will be either those who were decided well before the last day (for whom the theme is essentially meaningless) or down to pot luck if it’s a competitive bracket. You *could* monitor your bracket all day to try to keep your lead, but the effort does not justify the reward, so stuff that, plus you don’t have a lot of scope to keep yourself in the lead for 24 hours anyway. The basic tactic will be set yourself up, get screwed, and have no scope to do anything about it (or else choose a random time to run your visits, and just maybe hit lucky) Allies, and of course having multiple alts in the same bracket might make a difference, but that’s essentially the same as having the bracket decided before the last day anyway.
