Tikatus is a good midgame play. It's good in control match ups. But designing your whole deck around burning down your opponent's deck is kind of silly. It'll work against REALLY greedy decks, but you'll be dead in the water against any faster deck because you'll just be copying .
I think it's fine in a dedicated aggro demon deck (as a sort of pseudo-Bittertide Hydra). And then in slower decks as a tech for the control match-up.
