Pushing through damage will outweigh the two life they eventually gain
Why not put those lands to good use by sending them to your opponents doom
In a Commander deck lead by a legendary creature like Sythis, Harvests Hand, its easy to one-shot an opponent with Commander damage once your board has been developed
As if all that wasnt enough, Muldrotha also packs some tasty incidental combo lines
Since your main attackers are Basics, you can instantly recover with this one card, unless its Absol Prime and you have to wait a turn to attack
Plus, with two of them on the field because of the non-legendary token it creates when entering the battlefield, this commander also acts as a ramp to add colorless to your mana pool for an artifact spell or an ability when you tap either one
