For Vengeful Arbor, I may have had some fun with its Reddit post by parodying #drseuss and #thelorax:

As Des Slime provides archetypal support for Slime monsters by name, I figured I should provide some errata'd copies of Revival Jam and Jam Defender with archetype conditions clarifying that they are, per their Japanese names, Slime cards.

Also, I've started filling out the cycle of typal destroyed-by-battle searchers like Masked Dragon and Pyramid Turtle, starting with Rock, Fairy, and Machine monsters. I'll keep going with this cycle until all the Types have a searcher, so leave a reply if there's a type you want to see done first.

After some feedback on Reddit, I've decided to errata Malefic Horus' third effect so it can't be easily splashed and abused in non-Malefic decks. Now it'll require Malefic World on the field to activate and resolve, the same as Malefic Black Rose Dragon.

I also made some Dragon Lords / Felgrand series support cards, but I'll update their artworks as well to better distinguish them from their bases. Currently I'm working on a custom archetype based on Thunderbirds, and other singles like some Horus support and Monster Reborn variants.

I also designed Syzygy, the Black Sun Dragon, an Xyz monster based on solar eclipses.

You can find individual card images and design notes on my ArtStation profile, and can download all of my Malefic cards together from my itch.io page.

I also decided to switch from the TCG's PSCT formatting to a hybrid of that and the OCG's numbered effect formatting to make them easier to read and individual effects easier to find compared to the TCG's unbroken walls of text.
