Landfall is pretty easy to trigger with cards like Fabled Passage even in Standard, or creatures like Aftermath Analyst
This reason alone makes it one of the most powerful cards at your disposal, but the benefits hardly end there
Panharmonicon is still an $8 card despite seeing no competitive Constructed play
Enter the Infinite, unlike it's affinity-based cousin is a very good card and often does read You win the game. That is what you want if you are waiting till turn 12 to do something big (although you should always protect Enter the Infinite with at least one counterspell)
