It wasnt very good in an environment where creatures were hardly played and even if they were, your opponents would probably just take the cards anyway
Most decks set a benchmark for how many pieces of ramp they play not because they necessarily need that many, but to increase the likelihood of seeing some in the developing stages of a game
In order to express this mechanically, many of the Jeskai-aligned cards in this release have abilities that care about the second spell you cast in a turn
