Welcome to my cube! I would describe it as either an unpowered vintage or a legacy + cube. The vision is to evoke classic Magic, before the design vision of Modern Horizons and "now downsides all value" came to dominate game design.
There are a few house rules to enhance synergy and to give a leg up to older cards that can't quite compete any more.
Finally, two cards, one too good and one too bad, have been balanced by combining them into one new card:
UB
Psychic Tog
Creature - Frog Atog
Whenever Psychic Tog deals combat damage to a player, draw a card.
Discard a card: Psychic Tog gets +1/+1 until end of turn.
Exile two cards from your graveyard: Psychic Tog gets +1/+1 until end of turn.
