The owner of this deck hasn't added a sideboard, they probably should...

Submit a list of cards below to bulk import them all into your sideboard. Post one card per line using a format like "4x Birds of Paradise" or "1 Blaze", you can even enter just the card name by itself like "Wrath of God" for single cards.
Not really a deck, just a few quirky ideas I thought to use with Myr Welder. First: Giving Myr Welder charge counters could make for some interesting combinations, given which cards are imprinted on it. Outside of standard, this could become very fun, but for now, there's really only Chimeric Mass, Grindclock, Golem Foundry, and of course, Everflowing Chalice (*cough Myr Galvanizer cough*) Which brings me to my second point. Myr Galvanizer. Their card texts reads (if viewed under a black light) "Myr Galvanizer enters the battlefield with a huge target on its forehead." Myr Welder seconds as a back up Galvanizer if it is (or rather, when it is inevitably) destroyed.
