While sacrificing lands has its downsides, a Crucible of Worlds makes up for it, especially once you consider how much ramp Commander decks play
One such legend is Legolas, Master Archer -- a powerful card that provides a much-needed change of pace for green decks in most formats
Especially if so, in any case, you could just make a special rulling that decrees the card get requirements are higher and/or they are real and present like Tarjic, but not beholden to her like he is, and this can deny getting summoned if they are really busy, and/or she can be summoned by them similarly which adds extra consequences to Questers for getting them in our deck
During your next Standby Phase, add that card to your hand (this card doesn't have to be face-up to resolve this effect)
Bone Shredder: One bit of creature removal, and because it has the echo that well never pay, itll be in the graveyard to do it again
