Welcome back to the How to Play Magic: The Gathering series from Star City Games
Twenty-one total Lessons is all I could find that was even a little bit playable, and of those, several wouldn't be if you had to put them in the main deck
The Doctor Who Commander Deck includes 1 ready-to-play deck of 100 Magic cards (2 Traditional Foil Legendary Creature cards, 98 nonfoil cards), 10 Planechase cards, 1 six-sided planar die, a 2-card Collector Booster Sample Pack (contains 2 Traditional Foil or nonfoil special treatment cards, with 1 Common or Uncommon and 1 card of rarity Rare or higher), 1 foil-etched Display Commander (a thick cardstock copy of the commander card with foil etched into the cards border and art), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 Life Wheel, 1 strategy insert, and 1 reference card
From there he's a solid Planeswalker add to a Cat deck, though not necessarily a sick combo engine or anything
