Hey there everyone. Just to clear up any potential confusion: When we first talked about Jumpstart we mentioned that it will contain some Standard-legal cards (reprints from recent sets and M21) in addition to some brand new cards. No cards will enter Standard through Jumpstart. Additionally, all the cards in Jumpstart that come to MTG Arena will be added to Historic. Hope that clears things up!

Should be fixed in our May build; didn't make it in time for this one

Hawk is non-interactive in its own ways. A large Paradise Druid can be answered in ways a large Hawk can't - say, with a Foulmire Knight to block or a bunch of tokens to attack around it and race.

To be clear, all three of the decks I named were at levels that could justify some kind of action. We would prefer to hit a single enabler that crossed many problematic archetypes than do individual cards for each. This was an opportunity to do some good in a lot of places with (relatively) minimal upheaval.

We don't love doing preemptive bans, and this was locked in well before Ikoria even came out, let alone any specific piece of content. If this deck is as prevalent as the general expectation, there will be some action for next time.

Last time we ran an Artisan event, Hawk had a very high win rate and play rate. We were pretty surprised to see it, so we dug in a bit more, and it turns out it was a meaningful component of multiple top-performing decks: lifegain, enchantments, and flyers. The numbers were extreme enough that we thought it warranted action.
