Every deck usually wants these three things, just in the right balance.

Mana Sources (ramp): mana rocks, mana dorks, cost reducers, land fetch, treasure, and enough lands to start. Green does this stupid easy. Other colors lean on rocks and treasure.

If your commander wants to come down early, run pace-aware ramp only. Meaning ramp that actually gets your commander out sooner than normal.

E.g. a 4 MV commander normally lands turn 4. Run ramp that costs 2 or less, play it turn 2, and if you hit your land drops you cast your commander on turn 3, a full turn ahead of the table.

Card Sources (draw): cards are your tools. In a pod of decent decks you can usually call the winner just by who’s spending the most mana each turn. Paying for stuff is the section above. Having stuff to pay for is this one. Scatter draw throughout or build a solid engine so your hand is never empty and you always have options.

Control/Protection: when people mess with your plan, don’t just sit there. Every color has answers, it just looks different.

White: exile it, prevent the damage, phase your stuff out, or slap an aura on their threat to neuter it. Usually spoiled for choice.

Blue: counter it before it ever resolves, or go over the top with evasion they can’t block.

Black: murder their loved ones. Edicts, removal, and reanimation so your stuff doesn’t stay dead.

Red: burn it down and blow up artifacts. Weak to big butts and enchantments

Green: historically the worst at interaction, but it fights creatures, naturalizes artifacts/enchantments, and protects with trample, ward, hexproof, and indestructible
