CHARACTER SECRET LAIRS: HOMESTUCK

Here are some explanations for why things are what they are with these:

The name "John Egbert, Heir of Wind" is used because that is what appears in canon and admittedly, I'm still a little suspicious of Hussie's statement on "June Egbert" because it came off as a little too sassy, even though I like the idea. This alternate render is available if you prefer it. June is Naya because, while she isn't super-smart in the normal ways (not stupid, but not as clever as the two Dersites and lacking Jade's prophetic powers), she also isn't very selfish, cutting out blue and black easily. She is rash and temperamental at times, but ever a hero. The ability set is based entirely on the sylladex shenanigans from early in the comic, with a statline to make equipping Piston Sledge give her even stats.
"The Windy Thing" is Desert Twister not because of any theming with wind, but because it is mostly seen in ways that are destructive, such as drilling the Battlefield.
Rabbit Battery is a robot bunny, just like the Cyborg Bunny it represents. It also can be used to give another creature a boost of power.
The theming of Winds of Change should be pretty natural. The art choice is features Gamzee's eye in a cloud and is from a sequence around when God Tier June is walking the Battlefield. This moment feels like a pivotal one, when something has recently just changed, and Gamzee's eye shot is from right about when the Scratch happens, another moment when everything changes.
Fracturing Gust is a further allusion to the destructive power of Breath magic, and in particular alludes to the Choice given by Typheus. After warping away the oil, June plays a pipe organ so good that it blows away all of the glitches affecting Homestuck (as "special stardust", you can think of these as being Enchantment-flavored, I guess). (It's also the only one I can say the actual artist on for sure. I could credit most of these to Hussie probably, but I've chosen to not do that unless I have outright verification. The art from the Calliope section is explicitly credited to Shelby Cragg.)
Piston Sledge is obviously the Pogo Hammer. Nothing else to say here.

Rose Lalonde, Seer of Light is a double-faced card to represent her normal state and her state before and up until she goes Grimdark. As a Seer, her front face focuses heavily on interactions with drawing; her highly-aggressive magical powers give the rest of the ability its aggressive edge. The first ability is more of a unique protective ability fitting the theme. On the back side, she's focused on rampant destruction, as with her researching her session through breaking things. Annihilator feels like it fits, outside of flavor, best in black/red as an ability focused on reckless but potent destruction. The second ability is themed around the effects of Torment of Hailfire and synergizes with her Geth's Grimoire.
Jaspers, Twice-Beloved Companion is twice-beloved because he was Rose's cat and Roxy's, and he had two different names between them. Enduring Curiosity's revival effect works well with Jaspers' eventual nature as a sprite, and "Glimmer" is an acceptable creature type for this reason.
Geth's Grimoire is the Grimoire for Summoning the Zoologically Dubious. Knowledge of the things this is referencing is said to make one go insane; usually mill is themed as insanity, but discarding is occasionally too (although it's usually more like lobotomy effects, in that case). It fit in my brain, okay.
Forked Lightning is an oddball damage spell that can hit multiple targets, which fits with the visual (Rose, I think, doesn't fight 1v1 a lot) and emphasizes the aggressive nature of a lot of her early spell-slinging.
Dreadbore started out as Detonate to theme better with this moment (this is when she blows up Eridan's computer) but I decided to replace it with a card that wasn't smoldering dog-shit.
Fevered Visions very specifically refers to the moment she goes grimdark, but just generally fits with her calling upon the wisdom of the Horrorterrors and maybe reading that Grimoire too much.

Dave Strider, Knight of Time is a weird one. For a start, his second ability plays with the fact that there are a LOT of times when there are multiple Daves hanging out, but I didn't want to give him a full removal of the Legend Rule because he doesn't time-clone other people. His third ability does a ton because it's something that shouldn't happen very often under most circumstances, and to be fair, he doesn't have any sort of get-extra-phases effect in his SL. So I felt like it was fine to put this on something that feels undercosted. It of course is themed around time travel effects.
Dave's Timetables is obviously Time Sieve. Like, no shit it's Time Sieve. An artifact that gives you extra turns? What else would it be, Gonti's Aether Heart? TIMESIFTER?! I mean, I guess Magistrate's Scepter is an option, but I straight-up forgot about that in lieu of Time Sieve, a card that definitely makes much more of a splash when you see it.
Dave is a special boy so he gets a second aliased card, much like Captain America. Both the same character, you see. Lil Cal, Eternal Haunt is Stuffy Doll for many reasons. For a start, I keep forgetting Stuffy Doll isn't legendary for some reason. Second of all, it fits with the theme of it haunting a fairly specific person and also being a thing that causes many problems for anyone who it comes into contact with.
Chronomantic Escape was the first card I thought of for Dave. It's really, really good. I wanted to originally have a shot of him saving WV, but none of those shots looked good for what I wanted, or they had images that broke out of the border on MSPA and looked bad as a result. So instead here he is abjuring Karkat instead. Oh well. Still good card for him.
Temporal Extortion is chosen because of course Dave needs another extra turn card, but I thought just giving him a blue one was BORING. Temporal Extortion is really good and can be used as a burn option (because really who's gonna let you take that extra turn right), and it serves as a nice allusion to a place where you could probably imagine the story branching.
Brain in a Jar is a reference to, uh, that one time when Dave was messing with the Captcharoid Camera and figured out a way to alchemize a copy of his own brain. I think that only got used for the SBaHJifier, which was a one-off joke item. But to me, this just kind of sticks out as one of those particularly special weird things Dave did early-ish on, clone his own brain (or get into a position where he could).

Jade Harley, the Isolated was a difficult character to arrive at. I wanted to deal with her constantly adding more stuff to her form, becoming a First Guardian dog furry God Tier with Sprite powers... so I went with a modified Figure of Destiny design. Also, she had to die and be revived (as a sprite) for this all to work, so I think the death for "level 1" fits, right?
Becquerel, First Guardian's powers mostly manifest as Space effects, i.e. warping. Thankfully they printed a perfect card for this: a dog that blinks things. It's even delayed! Phasing would have not worked for me. This one just feels like a slam dunk. It's probably less cool than all that, but look...
Farsight Mask was one of those cards I just knew Jade had to have! I always associate her with that one image with the Dutton Glasses (note the flavor text), but of course there's something similar with her with the Spectagoggles, which actually DO SOMETHING, critically. And it's something you can parlay into being about card draw! I'm a genius. (Note: I'm actually a total moron.)
Radiant Lotus alludes to the Lotus Time Capsule, which Jade interacts with a nonzero amount of times. Plus you even feed it items. But for some reason they come out as Black Lotus mana in this case... which is highly useful, just like how it always seems to output the right thing at the right time, because Homestuck is a series of predestination loops vaguely shaped like a webcomic.
Wipe Away references very specifically Grimbark Jade sending away Dirk Strider, but can refer to any time she instantly warps items around. In particular, a split-second card is chosen because nobody responds to this bullshit in canon. I wanted an image of her manipulating the window but there are actually not as many of those that look good as you'd think.
Tempt with Discovery is mostly because I needed something to fit what I consider to be one of Jade's core visuals, i.e. here "juggling" the four planets and the Battlefield. This seems like it works fine as a land searcher, and having it be something big and audacious (for example, something which can, under the right circumstances, find you five lands) fits the mood of the visual. I thought about All Suns' Dawn, as well, but none of those are suns. (And because she's Bant, she can't use Conflux!)
