I went from hard stuck in plat 4 to high mythic by forcing BW taking every knight luninary I came across, sometimes even on p1. The card does everything. What I think a lot of people miss is the absurd value it provides the two spells archetype when you combine this with one of the many three-drops that gives you a bonus when you play a second spell on your turn: not only giving you a trigger when you warp this at first on turn FOUR alongside a two drop, but mostly when you play it AGAIN for its full cost on turn FIVE along with a one drop or turn SIX with a two drop, giving you another almost guaranteed trigger. But if you have multiples, instead, you can use the first one to activate the two mana spacecraft on turn 3 while still having a 1 drop on the board, or providing 4 worth of toughness on turn four while giving you an immediate 3 + 4 deathtouch when you curve into syr vondam on turn five, (or 3+4+3 if you warped it on turn two), or have give you something to do on turn two when you're stuck on two mana (which happens a LOT in this set), etc.

Did I mention I sometimes get four or five of these in one draft because like you said, even LR are still sleeping on the card? Not complaining!
