Walls of Arcades

Straightforward deck built around Arcades' ability to allow creatures with defender to attack and assign damage based on their toughness. Tetsuko allows all the creatures to attack without being able to be blocked, and +0/+X pump spells such as Dive Down and Aegis of the Heavens help push extra damage through. Walls are helpful against aggro decks, but enchantments and control-based Planeswalkers, such as Teferi, Hero of Dominaria, can be sideboarded in against control decks to help counter their control-ability, and Karn, Scion of Urza allows digging for more creatures as well as decently-sized artifact creatures. Shalai, Voice of Plenty also helps as a sideboard option for it's hexproof abilities.
