mtg core 21 card list Set 2021 Preview: Basic Lands 25 MOST VALUABLE CORE 2021

The ability to play cards that dont work in other formats is wonderful, but you need to get the mana to do so first

Not for me

You dont really need triple mana in Limited, though I suppose someone is going to Choco-Comet for X = 21 with Nyxbloom Ancient

Some color combinations simply dont have any mana ramp worth playing at all, either forcing you to consider extremely mediocre options or exclusively rely on single color cards and mana rocks to get the job done: Dimir (Blue/Black) Boros (Red/White) Orzhov (Black/White) Esper (Black/Blue/White) Grixis (Blue/Black/Red) Abzan (Green/Black/White) Sultai (Black/Green/Blue) Temur (Green/Blue/Red) Most 4-color groupings That doesnt mean all other color combinations have amazing ramp options though many can only offer situationally powerful cards
