Thats what makes it extra crazy that the early days of Magic had tournament-legal cards that did exactly this kind of thing
These cards include tutors to find your key cards, the key cards themselves, and any supporting elements to improve your chances of winning
Strionic Resonator was the first to do so for triggered abilities
The vast majority of these planeswalkers are now stuck on their own home planes (the lore justification is it was natural for most 'walkers to return home during the fight)
This Duskmourn: House of Horror Endless Punishment Commander Deck includes 1 deck of 100 Magic cards (98 nonfoil cards and 2 Traditional Foil Borderless Legendary cards), 10 Archenemy cards, a 2-card Collector Booster Sample Pack (contains 1 Traditional Foil or nonfoil alt-border card of rarity Rare or higher and 1 Traditional Foil Uncommon card), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 Life Wheel, 1 strategy insert, and 1 reference card.
That alone has made this unique design sought after
