All three of these cards are a great fit. Scrapwork Mutt feels like it makes sense anywhere. Rummaging is a great mechanic I'm happy to have more of and same goes for the graveyard potential of that and Combat Courier. Thopter Mechanic fits in with those mechanics as well, rewarding sequencing effects around it and making one of the three allowed tokens.

Adding two cards that were missing from the list.

With this update I fixed some inconsistencies between the digital and paper list. From the digital list I removed a few accidentally left in cards, and missing cards I've had trouble finding. From the paper list I've finally added the suite of thopter cards.

I've added back Radiant Flames which was left in the paper list. The card is a bit over powered and often decides games, but I do still like having a few higher variance cards that can swing a game.

I like modal cards like Wasteland Viper in this context, but I really dislike bloodrush can only be used on attacking creatures which has caused some confusion and misplays.

Removes a handful of cards of a few types, including some too-easy two for ones and situational cards that just led players to spin their wheels. Fungible tokens have been removed swapping a few goblin cards for thopters.

Green is a bit hard in battle box. A few of it's major strengths - ramp, land interactions, diverse tokens - are all things I'm trying to avoid in this list. I don't need the colors to be perfectly balanced, but want it to be enough so that there isn't an advantage to knowing to start with particular lands since you're more likely to draw a particular color.
