Here's how I would evaluate these decks on first glance.
Titans: Not recommended, but maybe as last resort. Imo it would lose to 3/5 of Darkness's winning decks, Mono, Ghostmare, and PU LS Drags.
Ghosts: Bump it up to 5 Wings, and then we'll be talking. Only then can it dominate their Time duo.
Dims: Not bad, but I feel that a speed Grabbow would be stronger.
