Any thought on that the lack of land destruction means expensive cards that would in past formats be unplayable become staples due to their more powerful effects and by default makes ramp (even temporary like treasures) the key to leveraging these powerful effects and land with useful abilities? Formats with decks built around cards like Aetherworks marvel, Fires of Invention, Wilderness Reclamation, Field of the Dead which can leverage more powerful expensive spells earlier seem to show a gap in development understanding of unintended consequences, any thoughts on that?

There’s an alternate world where decks that keep players from ever playing cards exist and Magic is way lower on net fun. Also, when asking questions of the people that make a game, why not assume that they might know things you don’t rather than presume they’re making mistakes?

I still find the artifact = problem correlation weak, at least as it relates to their colourlessness. Aetherworks Marvel used a mechanic that tied it to a colour combination; it would still have been problematic if it were a UG coloured artifact, and it became a problem with the printing of Rogue Refiner, a nonartifact. Smuggler's Copter was such an obvious error every commentator it raised it as a concern on sight. Artifacts are a scapegoat for Kaladesh's flawed design, not the cause.

Artifacts aren’t to blame for Kaladesh. Or Scars of Mirrodin. Or Mirrodin. Or Antiquities. It’s the individual design of each of those sets and not the mechanical connection that binds them all together. And it’s a complete coincidence that the one set with an artifact theme that was woven into colors (Shards of Alara) is the only one not to break. : )

I assumed Spike was a wish (the text sure looks like one) so couldn't grab cards banned in the format your playing, but could grab cards banned in other formats. Like in Un-Standard could grab Baral (banned in Brawl) and in Kerfuffle could grab Aetherworks Marvel (banned in standard), is she supposed to actually grab things banned in format? How does this work if your format uses a sideboard?

Spike gets banned cards, so it makes sense Spike could get cards banned in the format you’re playing.

When looking at the top n cards of your library, why do some cards allow you to put them on the bottom in any order (like Collected Company), while others specify a random order (like Aetherworks Marvel)?

If it’s just a few cards, we let you order them but if it’s more than that we make it random to avoid making players spend brain energy on it.
