"The Wilds and the Deep" features the *monstrosity* ability, which allows you to pay a lump sum of mana to permanently increase a creature's power and toughness. Just when your opponent thinks everything is under control, your monstrosity creatures can grow to unfathomable size. Power out your large monsters early, and make them unstoppable late.

Golden Hind, Kiora's Follower, and Font of Fertility can come out in the first few turns and help you cast your large creatures more quickly. Creatures like Swarmborn Giant and Sealock Monster will likely be bigger than anything your opponent can muster when they hit the battlefield, and their monstrosity ability allows them to keep pace as the game goes on. Archetype of Imagination lets you get past ground stalls by taking flying away from all of your opponent's creatures and granting it to yours.
