In reality, while it certainly introduced some new toys for the format, a lot of people associate the set more with the likes of the banned Hogaak, Arisen Necropolis, the obnoxiously expensive Force of Negation, and some really cool Commander cards
It takes little effort to get multiple landfall triggers, so this takes over games in no time
Assumably, cards with the Vanish ability will synergize with those cards, making it easier for those effects to go off
It effectively makes all instants and sorceries you cast cost 1 less, which looks very nice with cantrips like Overmaster and Expedite
It can be OK as a cheap mini wrath for a control player who can get some use out of the other ability with tokens etc but at that it is not worth a cube slot, certainly not a gold one
The triggered ability of the "partner with itself" keyword still triggers in a Commander game
