kenrith can be a serious threat, and i've seen tuned lists for it, very easy to win. However, i have to rely on my reputation at my LGS for that one if i do it.
I'm less known for my good decks and more for my Zedruu, the Greathearted, which notably doesn't run your typical rust elemental, steel golem, illusions of grandeur, aggressive mining, etc. Pure group hug. The only way i can win is felidar sovereign, with no ways to protect it in deck. Dumb decks like that mean people generally trust me when i say, "this deck is going to do this, and not this"
