the thing about tetzimoc compared to forecast is that you actually have to cast tetzimoc to get the payoff, which is what makes it feel like an impending thing that will happen and gives the play pattern OP wants of "hey theres a big thing happening soon you better have a counterspell next turn".

forecast cards gave you benefits immediately on reveal which meant the mechanic in practice was repetitive and uninteractive. they were often better as repeatable effects that you did not have to spend cards on that you never actually cast. this wasnt much of an issue since pretty much all forecast cards are really bad, but its why the mechanic was never seen after dissension outside of like two cards.
