Heres a practical skeleton that keeps you honest: The role buckets Mana (lands + ramp + fixing) Card flow (draw, rummage, impulse, tutors if your group likes them) Interaction (spot removal, counterspells, protection, wipes) Plan enablers (the cards that make your deck your deck) Payoffs and finishers (how you convert setup into a win) Utility (grave hate, recursion, flexible tools) The exact counts depend on your commander, curve, and pod
Something else to keep in mind is that even though this is a new way to play Magic, its not the first time this concept has been introduced
It has to be a creature that died the turn this enters, but the reward for timing this right is a stack of treasure and a small bit of graveyard denial
Commander Legends is the last supplemental set that has been announced for 2020 so it seems like one of the final places for the fetches to be printed
Make sure you're constantly swapping cards in and out of your deck based on what you learn
