I play a variant of Devoted Druid called "All In." This is not the only version of Devoted Druid combo.
I believe it is the best version of the deck, and I'm not interested in discussing that point much; if you want to find people who like other versions better, it will be easy to find them. Use channels on the Discord.
I will mostly be found in #all-in-druid. Other channels include #finks-company and #stoneforge and there are lots of others too. If you have questions about those lists, ask someone else.
Our backup plan if the combo isn't working is to protect a Shalai, Voice of Plenty, which is a Flying, 3/4 Gavony Township Leyline of Sanctity, and if that isn't enough for you, then go cast a Kitchen Finks or put a Batterskull into play and live your best life. I won't judge you; I'll just threaten to kill you every single turn until the game ends.
