For the Ancestors is a typical example: It allows you to look at the top six cards of your library and put any number of cards from a specific creature type into your hand
Their use cases go up in graveyard or flicker decks, of course
Look for these tip offs and you can avoid being ripped off: This has one more error so blatent, that it alone flags it as a fake
This makes Nibelheim Aflame much stronger in decks that mill over cards, Loot, Rummage, or have any synergies with the graveyard
While Rhyss tokens had tribal synergies, green doesnt have a ton of artifact-enabling monocolored commanders, so the ability for [casthaven]Oviya Pashiri, Sage Lifecrafter[/casthaven] to pump out artifact tokens is going to be strong in any deck that wants to play in that space
I know not every Commander fan has been happy about the level of attention that WotC has given our favorite format since the first Commander precon products rolled out, especially since there have been plenty of design mistakes along the way
