It's a little more complicated than that. Here was my thought process:
I expect
chancellor of the annex to be a thing, so I wanted at a minimum to have something to pitch to it. Basically, I decided that pitching something to it was better and faster than trying to build in excess mana. HOWEVER, I did not want the card to be useless if I didn't run into
chancellor of the annex decks, and I wanted something at a minimum that could take out a
chancellor of the forge token to spite
foil. This already leaves a limited number of options, but I had OPTIONS. There were multiple things I was considering, from having my threat deal with small creatures to other alternatives.
Then, I looked at what decks I thought were going to see play. 2 big ones right out of the gate that are also reliant on 1/1's are
chronomaton and
inkmoth nexus. Both were going to be really well placed in the meta, which makes it even more important to be able to kill a 1/1
at instant speed. Our number of options have gone down significantly. When you get to the fact that i expected to see multiple smaller creatures, I decided I needed some sort of way to block and deal with small threats. And..... after a few more decisions down the road we get to scavenger gut shot. I thought I could block most things I would deal with and blow up a few I couldn't for a tie
. But I picked the thing to be an anti nexus/chronomaton card, not an anti forge card. Anything that could deal with those via damage can deal with forge.
Razorborne out-thought me even more though
. I knew there were going to be very few actual channex decks and almost no foil decks, but I didn't expect anyone to flat ignore the possibility.
