Quite substantially so

It has an end step trigger that costs a discarded card to create a Treasure and seek another card, depending on your choice of ambitious or expedient

This deck-building challenge helped me understand which cards Wizards of the Coast and players value highly enough to keep around in competitive play (such as Giant Growth and Birds of Paradise) and which cards just couldnt hack it through the years (such as Aspect of Wolf and Stone Giant)

That being said, its versatile enough that you can use it as a three-mana Mana Leak against slower decks that you may struggle against

Its much worse, but in a vehicle deck, adding to your board while disrupting theirs can be very effective

This prevents you from blowing out six or eight lands in a couple of turns barring anything obscene
