Felidar Sovereign and Aetherflux Reservoir are the win conditions. The point of the deck is to stall and gain life until I can get a Reservoir and/or a Harness the Storm on board, then either win with 30 life with FelSov or tap the Reservoir to do 50 damage.

The Reservoir says, "WHENEVER you cast a spell, gain 1 life for EACH spell you've cast this turn." So if I cast Bomat Courier, then before the Reservoir's trigger resolves I respond with a Galvanic Bombardment, then before that trigger resolves, using Harness the Storm's effect I cast 2 more Galvanic Bombardments, I will gain 4 life for each spell I've cast this turn, and before the triggers resolve I will have cast 4 spells. 4x4=16. If I cast 5 spells, it becomes 25 life. Six spells = 36. I only need 30 life to win with FelSov or 50 to win with the Reservoir.

Bomat Courier, Cathartic Reunion, and Not Forgotten let me put a bunch of cards in the graveyard while I search for my combo pieces. Fumigate, Galvanic Bombardment, Authority of the Consul, and Blessed Alliance are all control/removal tactics until I can get the combo on board.

The rest of the creatures are just chump blockers and alternate win-cons if my opponent destroys my combo pieces.
