When all 15 gods are on the battlefield you win because they are all creatures.

Deck List block version.

15 gods; 12 mana dorks and more mana fixing; Prophet to speed it up.

Heroes' Podium tutors the gods. After all 15 are on the battlefield, each god gets +14/+14.

Note: Follower allows you to untap Podium or Cornucopia.

Win con:

all 15 gods plus Prophet of Kruphix, mill because of Phenax each opponent during their upkeep. (mill is for over 285=(5+14)15 with Podium) It is better than attacking.

Here are some notes of keeping track of the tiggers from all of the gods:

Group them by type: upkeep and draw effect, combat, static/activated, creature enter battlefield, creature leaving the battlefield.

Group 1 upkeep and draw: Ephara, Mogis, Thassa, Keranos

Group 2 combat tricks: Xenagos, Iroas

Group 3: Erebos, Heliod, Nylea, Kruphix, Phenax, Pharika

Group 4: Karametra, Purphoros

Group 5: Athreos

Also note: everyone expect Heliod has vigilance and everyone expect Nylea has trample with Purphoros as your mana dump.
