Moving to a three-year rotation and adding Foundations creates a broad, stable base to build upon along the same timeline of regular Magic releases, and Universes Beyond sets will deliver more cards to the format than ever before
There are also more direct ways to defeat your opponents by giving them stuff
His card in Beyond Death isn't something to cast aside, though
The life gain drawback becomes negligible in multiplayer formats where games last longer and life totals matter less than board control
Not only are you triggering your lifegain synergies, but drawing when you gain 3 is easy to trigger with Food tokens or by attacking with an okay-sized lifelink creature
In fact, in Legacy, I board it in against both Death and Taxes and Jeskai Control even though neither deck really interacts with their graveyard, simply for the previously mentioned reasons
