From the stream and sand to the desolate landscape, there is a lot here for me to recommend
Otherworldly Gaze If you count Surveil spells as self-mill (and I do, given how rarely you see triggers that care exactly how cards end up getting from your library to the graveyard), then Otherworldly Gaze is as good a choice as any for the most consistent, efficient, no-bells-and-whistles version of the effect
While Disney Lorcana puts plenty of emphasis on gameplay, its cards have great collector's value
A spell's mana value is always based on that spell's mana cost, not any additional costs you pay
Agent of the Iron Throne is a redundant effect for any number of aristocrats commanders, and one thats sure to see some play
Even just drawing with this once and forcing a trade seems good, and sometimes it will run away with the game Im not usually a big fan of tricks that grant hexproof, they are just too situational
