A 4/4 is fine, if a bit sad against Sheoldred, and its ability to Shock something whenever you cast a spell should be able to close out the game quickly, assuming you have some cards in hand
It asks you to play control, but also gives you cards for your troubles solving one of the issue with control in non-blue decks in Commander
Unlike some of the other uncommon commanders, they have trample, letting you grow this creature and smash in
If you control a Legendary creature, the Shire immediately enters untapped and can tap an untapped creature to create a Food for two mana
Its all enjoyable, and helped here by the gameplay on offer, but future sets may struggle to draw people in in the same way as universes with a bit more charisma
