Midrange deck I made with artifact creatures, used mostly white with a splash of black. Not the first deck I came up with but it's the first deck I made and developed completely on my own. The deck was called 'Catfinity' for a long time before I came up with the current name.
Leonin Elder gave me the idea for the deck. That 1 life/etb eventually makes a difference (and it also triggers when my opponent plays an artifact). Below I've written down the deck's history and I linked a version I made for Pauper.
2015-2017: I was introcuded to MtG by kitchentable magic.
2017-2019: We started deckbuilding with a friend and I also made this deck by myself, from cards I had at home. I remember finding Lenonin Elder, Hunger of the Nim and Darksteel Citadel and getting the idea for it. I kept developing it and it became the first deck I completely owned. Chief of the Foundry was the first playset I tried to find for it and eventually I did.
2019-2021: We played less and because I got addicted to the game I started playing Pauper, still as a brewer. After playing the format for a while I realized that this deck could have a Pauper version with some modifications. I bought 2 more Leonin Elders (this version doesn't need 4 but a Pauper version does) and other cards for it. I bought the OG Artifact lLands too. I only played that version once but I kept the artifact lands in the deck. That was when Mukotai Ambusher was introduced too. When MH2 came out I included a playset of Goldmire Bridge as well.
2021-2024: I played the deck when I could, with small upgrades every once in a while. It was called "Catfinity" before.
2024: My brewing years in Pauper were nearing their end. I grew tired of it as the format got more and more competitive. I found new cards since playing this in Pauper the last time. Refurbished Familiar was the card that made me consider a Pauper version again. I decided to re-brew it and play it in November as my last homebrew Pauper deck. It was fun but not very succesful. This is how that competitive version looked: https://tappedout.net/mtg-decks/body-brothers-dead-deck-1/
I also didn't know about Glaze Fiend the last time, which is a must have in a deck like this and Mandible Justiciar came out too. The name 'Body Brothers' came to me when I realised that this was an artifact version of the 'Soul Sister's decks (in which Cleric creature's abilities trigger when creatures etb, while here creatures trigger when artifacts etb. Soul Sisters -> Body Brothers, get it?) and I liked this new name better than 'Catfinity'.
When the new Pauper version's career was over it was time to rebuild this version. I didn't make it exactly the same, the Pauper version influenced this one too. I wanted to keep some of the "artifact etb" stuff from that gameplay. I didn't want to keep Refurbished Familiar because it doesn't fit the kitchentable version, it's either too OP or too weak. But I definitely wanted to keep Glaze Fiend and Mandible Justiciar as 2ofs. Pierce Strider was a 4of but it became a 2of. Took out one of the two boardwipes. With the changes the deck is somewhat more agressive now. I also added Pactdoll Terror a few months later, as the last important "Body Brother" type of creature.
I started making sideboards for new casual decks I made in 2024. This deck was in Pauper too before, like some of those new decks, so it also earned a little sideboard; 3 cards remaining from the Pauper days plus a new one.
Now the deck has it's new name and it's final form. My good old Catfinity / Body Brothers deck, still here after all these years, going through some changes but always keeping the same spirit.
