I got my N4 on JLPT a few months ago.
Still not disillusioned by Anki.
It's obviously not much and it's definitely a decade away from understanding even the simplest of games but it's a surprisingly fun process as I'm playing some kusoge or watching anime and noticing words that I now know.
頑張ります!

Play Magic the Gathering Forge, you can find it for absolutely free on github and it's THE best way to play modern magic right now.
alternatively play Magic the Gathering Shandalar (2016 modded version, you can find a link to it in vee archives IIRC but I recommend Forge over that unless you want to play old magic)
Stay far away from Arena and other online MtG games. Maybe the early 2010s Planeswalker games are fine too, but the rest is total garbage or ridiculously predatory.
>YGO
Emulate a PSP and play TagForce 1,2,3
Play the Joey the Passion trilogy games (really outdated, but good music and visuals like you'd expect from YGO, you might need compatibility patches for those)
Master Duel is okay but it still has predatory practices and while I'm okay with that in terms of physical cards for both YGO and MtG, I find it appalling in digital card games, so I'd also advise against it even if it's the best bet for modern YGO.

That's it, you're up to speed. Have fun.
