I mostly play Magic with people that I’ve taught the game and gotten hooked on it. Because of that I always keep the new player experience in mind when building decks and some of them are even built with that as a hard constraint.

These are the decks I keep that I give to newer or rustier players. They tend to have a bit everything or else commit hard to just the one theme where the theme is obvious.

Halana and Alena Counters - Make your commander big then they make something else big every turn.

Sloguurk Self-Mill - mill yourself, make your commander big, draw lands from the graveyard, play them.

Ramp City Svella - Ramp ramp ramp, cast fatties, profit.
