Counters in Commander
Ever since seeing evolve, I've wished I could play with it and graft together, just for more fun with counters. Unfortunately, most of the creatures with graft aren't very good by today's standard, so I can't really build around that in Modern. Fortunately, this is why casual formats exist.
Building casual decks is hard for me. I tend to make them too “Spikey” and they become less fun. A trick I've learned to avoid this is to give myself serious restrictions in deck building, so that even the Spikiest deck I can build will still be weak enough to let everyone have fun. Another tool I've developed is to heavily push a theme, so I can still have a goal or focus in deck building, without focusing on building the strongest possible deck. It's necessary for me to have a target in mind when building a deck, otherwise I don't know how to make any choices.
This deck is a product of both of these methods. I've restricted myself to only lands, creatures, and the card Doubling Season, and I've built a deck with the goal of playing with +1/+1 counters as much as possible.
I'm confident the result would be a blast to play if you own a lot of dice and have a group of Commander players with have less powerful decks—and if you need to need to make it a little more powerful, it's easy to just throw in a Sol Ring, Sylvan Library, or any other Commander staples you happen to have and like playing with.
