The second-to-last slot, with nonfoil borderless anime cards or the shockland, is the best bet because of what it has, but at the same time, because theres less options theres going to be that many more of the cards
And that's the story of
Lorcana Troves For each of the Lorcana sets I buy a Trove as these are great storage boxes that are already themed towards the set
It also gives you mana towards them, in increasing quantity each time
Prince Naveen Ukelele Player 205/204 Im going to go out on a limb and say that Prince Naveen is going to be a long term chase card from Shimmering Skies
Sure, you've got your "all other [creature type] get +1/+1" baseline, but going back to Lord of Atlantis in the beginning of the game the coolest lords were always the ones that granted a unique tribal effect, and that's especially true when it's something that leans into their unique identity as opposed to something generic like first strike of hexproof ala Drogskol Captain - something like Rage Forger has always been a more interesting design
