After making another big update, thought I should finally post my mod here.

[ok wow]

Unlike mods that simply enhance and build off the base game like Requiem, this is a very different experience: it's an attempt at rebalancing the game while only staying in the DM/ GX / 5D's eras (plus several cards I splashed in from later eras). It's got 32 hand-made packs that are more or less recognisable compared to the TCG's releases (though the first bunch are significantly different), over 1000 cards have had stats changed in some way (while typically staying true to their purpose) and the campaign has been redone to work alongside the custom packs so that playing the game with your own decks feels rewarding and not like cheating. There's a lot more viable decks now, your opponents only have access to the same cards as you, and I swear there's definitely at least one person who thinks it's fun, so check out the mod page if you're interested!
It also has a multiplayer-only mode if you're looking to only play it with a friend :)
