4 strategies for this deck. Since Tinker is involved 4 times, it is literally a deck to play at home. However, with a sideboard switch, it could be legal to play in certain tournaments.

1st condition is to pull Darksteel Colossus out as quickly as possible with the use of Tinker. By turn 4, you should be able to hit with him.

2nd win condition, With Thran, Temporal Gateway, you may be able to draw into darksteel forge, play it from your hand, and overrun your opponent with thopters.

3rd win condition is to lock down your opponent with Icy Manipulator, Winter Orb, and Voltaic Key. I've been able to do this successfully multiple times, especially with gilded lotus on the field.

4th win condition ( i still have yet to pull this off as I'm still working with the balance) The idea is to use efficient construction, artificers, etc to spawn thopters. Useing darksteel forge, and Hammer of Purphoros, the idea is to basically overrun your opponent with indestructible flying 1/1 creatures. With the help of Master of etherium, it's easy to give each thopter a +1/1 or +2/2 (depending on how many master of etherium cards are on the field). I've only ran a few games this way and have won against my buddies tron deck (~20% wins)
