Thanks for posting this. I've had this, uh, 'discussion' with a number of shops that had proposed to launch Pauper nights and I try to ask them "MTGO rules or actual-paper printed rarity", they go "Whatever, if it was ever a common it's good unless it's on the banlist, if it was bad it'd be on the banned list", I explain "Hymn and Sinkhole aren't on the MTGO banned list because they're not MTGO commons..." "Whatever, man. We'll see how it plays out." Yeah, I already know how this plays out.
I don't want to bring a deck with Hymns and get in arguments with the faction that thinks they're illegal in paper pauper (not on the MTGO pauper valids list). I don't want to bring a deck with Chainer's Edicts and get in arguments with the faction that thinks they're illegal in paper pauper (never printed as paper commons). I don't want to bring a deck that resists using either flavor of corner case and then face decks all evening that didn't hold themselves to the same deckbuilding restrictions. I want a show-runner who gives a damn enough to make it clear to all players what the cardpool is; ideally, I want the organization that handles all the other formats (including the online version of Pauper) to actually give a damn enough to codify a ruleset for paper pauper. But for some reason they never do.
& 3, even if you had Argothian Elder and Wirewood Lodge, if you don't have a land that produces more than a single mana or something that triggers off an ability activation or tapping or untapping, this 'go infinite' doesn't actually *do* anything but let you turn your cards sideways and back an indefinite number of times for no benefit. The Wirewood Lodge costs a G and tapping itself to untap an elf, so unless the other land produces more than just a G, it's an infinite useless machine.
Hydroid Krasis is probably reason enough we don’t need that in this standard.
That said, I wouldn't be surprised if this became an every-commander-precon-inclusion taking over the slot that had, to date, been used on Sol Ring.
While they don't actually administrate either Commander banlist, it probably irks them that every commander deck they print is duelcommander-illegal out of the box and if they can conveniently change that (by no longer jamming Sol Ring in every deck, but replacing it with a card of comparable demand and utility), they might.
While we're in christmasland, three leylines (!!!), a Scuttlemutt, and Gauntlets of Light gets there too.
That walker was already in the graveyard before any player even got priority to cast a spell like this. What happens to the ability on the stack doesn't change that the walker is already long gone.
You also need some way to make this a little tougher, because Nova Chaser's toughness is equal to Thunderkin Awakener's, and you need the graveyard creature to be less-than Awakener's.
