"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.
Your other spells work particularly well with your larger creatures. Time to Feed lets you remove creatures with flying or other types of evasion that might otherwise be a problem for your grounded monsters. You can use Savage Surge to surprise your opponent with a huge blocker. And Hubris can make your opponent regret trying to block your large attacker with two smaller creatures.
Kiora, the Crashing Wave, a planeswalker from the Born of the Gods set, makes a great addition to this deck. She lets you neutralize your opponents' threats as well as draw extra cards and play extra lands, all building toward your inevitable mass of big creatures. If you're looking for more ways to cast big creatures ahead of schedule, Sylvan Caryatid, a Theros mana-producing creature, can help you out.
