MTG Arena has some lower power game modes that are nice.

“Jump in” where you get to pick two half decks and combine them to make a weird deck. They even have “Jump in” with lord of the ring cards. “Draft” Where you you make a deck by picking cards out of like 8 packs, so your deck is always going to be unique and janky and lower power, since it’s not the best combo cards from 10 different packs. “Starter duel” Where players pick one of 10 decks to play against each other, and the decks change.
