Some questions are better left unanswered, such as "Why does this deck exist?"
Just to be safe, I censored the title. I would hate to see this deck removed for a literary reference.

Strategy

The end goal is to cheat a copy of Colossification onto an unblocked attacking creature. The deck also must use fish tokens for this because reasons.

• Attach Arcanum Wings to creature who will attack unblocked >> Activated ability: swap with Colossification
• Academy Researchers >> Battlefield trigger: enchant with Colossification >> Cast Aura Swap to change target to unblocked creature

Exotic Pets is the most consistent way of acquiring fish. To synergize with our fish, copies of Curiosity and Combat Research are provided for quick and easy card draw engines... if you have fish or flying lackeys, that is.

To get there, we employ four copies of Open the Armory to acquire these enchantments. It also enables a small toolbox of auras:

• Aqueous Form: No fish? No problem. Just make Academy Researchers or Expendable Lackey unblockable.
• Eel Umbra: Need to protect your creatures? This fish-themed umbra has you covered!
• Staggering Insight: Follows the trend of damage >> draw triggers, but with added lifelink.

Sideboard

If you want to be toxic, Mana Tithe. Nothing feels worse than getting white-counterspelled (except maybe green).
Triton Shorestalker is admittably better than Expendable Lackey, but why not include both?
The Reality Chip may seem strange, but it is yet another toolbox option for Open the Armory. Running only 11 sources of creatures can lead to some catastrophic hands, but tutoring up a creature - or equipment in this case - can save you from some stinker hands.
Nomad Mythmaker seems like an obvious inclusion, but this deck is fairly narrow-minded. One Colossification should be enough.
Sleep with the Fishes is there for more fish (duh) but also as a means of removal; also a toolbox option.
Reservoir Kraken is... a thing.
