ramp cards mtg Top 10 Best Mana in MTG Cube: Archetype Breakdown: Green
Description
granting access to a Karnboard of toolbox artifacts just provides so much flexibility for a deck that only has a few flex spots and doesnt really want a traditional sideboard anyway
These days it sometimes sees some fringe sideboard play in Eternal formats, but other than that its just collectability

If you have enough artifacts in play, youll be able to draw two cards for only two mana

For instance, if Lorehold's effect was a loot (drawing then discarding) instead of a rummage, the combo wouldn't be nearly so clean (it would still be powerful, just a little easier for your opponents to disrupt)

It answers basically anything, and that flexibility is great
