It's kinda hit and miss sometimes, I can usually get it set up around turn 5 to 7. So not nearly as fast as a lot of vintage combo decks, that's why I set it up to be in the modern format.

The plan is to get your blinkmoth nexus into play and enchant it with dawn's reflection. Tap the land for 3 mana, use 1 to turn it into an artifact creature and 2 to untap it with voltaic constructs ability. You net 1 mana of any color each time you do that combo. The tutor, fabricate and expedition map are to help you get the combo into play, then you use your draw cards to pick up you whole deck, teferi and counters to keep your opponent from casting, then a solarion with boots to gain haste then swap the boots to another creature so you can keep tapping/untapping solarion until the desired number of counters, helm to give him trample in the event of any blockers and kill. The trickbind and azorius guildmage are in the sideboard in the event that your opponent has abilities in play that interfere with your combo.
