No description. Just check out what I did in a few turns...
Key: (Parenthesis) = description, cards drawn
No Parenthesis = cards played
Hand - 1 Plains, 1 Swamp, 2 Islands, 1 Vectis Dominator, Esper Stormblade, Ethersworn Canonist
1st - (drew Steel Overseer: 2, 1/1, Tap to give all Artifact creatures +1/+1); Plains
2nd - (drew Etherium Sculptor); Island, Etherium Sculptor
3rd - (drew Armillary Sphere); Swamp, Armillary Sphere, Ethersworn Canonist, Steel Overseer
4th - (drew Steel Overseer); Island, Vectis Dominator, Esper Stormblade, Tap Steel Overseer (Etherium Sculptor - 2/3, Ethersworn Canonist - 3/3, Steel Overseer - 2/2, Vectis Dominator - 1/3, Esper Stormblade - 4/3, flying)
5th - (Voltaic Key); Voltaic Key (0 mana cost), Steel Overseer, Sacrifice Armillary Sphere (obtain Island, Plains), Tap Steel Overseer (Etherium Sculptor - 3/4, Ethersworn Canonist - 4/4, Steel Overseer - 3/3, Steel Overseer - 2/2, Vectis Dominator - 2/4, Esper Stormblade - 5/4)
Because you shuffle your library after sacking Armillary Sphere, I don't know what you would draw this turn. What I do know is by this turn you would have already won. You will have 6 creatures on the field that have at least a 4 power (potentially 8 maximum power). Since you'll tap both Steel Overseers, you can only use 4 creatures. If they have any serious creatures, tap them with Vectis. If they have more creatures or you want to boost your artifact creatures even more, you can use Voltaic Key. So for sure you'll have: Etherium Sculptor - 5/6, Ethersworn - 6/6, Steel Overseer - 5/5, Steel Overseer - 4/4, Vectis Dominator - 4/6, Esper Stormblade 7/6 with flying. That's 22 damage right there. Hopefully you had already started attacking prior to this turn. So yeah. At this point, you hand shake the other player, GG and you feel good inside for winning with an Esper deck. :p
