Standard budget-friendly deck. This deck is deceptively fast and strong, with big creatures swinging in as soon as turn 3. Here are a few scenarios:
Scenario 1: (not too bad)
Turn 1: Mountain or Island (1 land), tap to cast Springleaf Drum
Turn 2: Mountain or Island (2 lands). Drop an Ornithopter, tap it and the Drum along with both lands to cast Illusory Angel.
Turn 3: Mountain or Island (3 lands). Cast Ensoul Artifact on Ornithopter, swing for 9 in the air.
Turn 4: Land drop, swing for 9 again. 2nd main phase Magma Jet or Shrapnel Blast. GG.
Scenario 2: (looking pretty good)
Turn 1: Drop Darksteel Citadel, cast Springleaf Drum
Turn 2: Island, Ornithopter, tap it for the Drum and cast Ensoul Artifact, swing turn 2 with a 5/5 indestructible Darksteel Citadel. Swinging for 5 every turn beginning on turn 2 is a pretty short clock, especially if you have burn spells to cast over the next couple turns.
Scenario 3: (probably my favorite)
Turn 1: Land, Springleaf Drum
Turn 2: Land, Generator Servant
Turn 3: Land, cast and tap Ornithopter for 1, sac Gererator Servant for 2, and tap three lands for a hasty Scuttling Doom Engine. Swing 6 and watch opponent scowl while they check their hand in desperation.
Turn 4: Land, then lots of options:Ensoul Artifact on Ornithopter, swing 11 (all evasive to some degree, 17 total) then Shrapnel Blast for GG.
or
Polymorphist's Jest makes your doom engine unblockable, swing for 6 again (12 total), then Shrapnel Blast your engine to hit for 11 (23 total). GG.
Honorable Mention:
Turn 1: land, ornithopter
Turn 2: land, Ensoul Artifact on ornithopter, swing 5
Turn 3: land, Generator Servant, swing 5 again
Turn 4: land, crack Generator Servant, drop a hasty Crackling Doom Engine, swing 11. GG.
Sideboard choices (very flexible list for now):
Polymorphist's Jest+Scouring Sands is a 1-sided boardwipe turn 5 (or earlier with a Generator Servant or Springleaf Drum out).
Negate comes in against control decks to protect the win-cons when casting them. Keranos, God of Storms would also come in against control just to help speed up the clock mid-game and ensure that I don't lose because I'm top-decking lands. I don't envision it ever becoming a creature.
Tormod's Crypt is there for graveyard shenanigans and also provides a free target for Shrapnel Blast.
Curse of the Swine serves two purposes. First, piggies can't block Scuttling Doom Engine. Second, it's great spot-removal against big creatures that would survive burn spells and "exile" instead of "destroy" is nice especially against the gods of Theros.
Suggestions, feedback, and +1's welcome!
PS: Really looking forward to Mindswipe from KTK, I think it would take the place of a couple copies of Dissolve in the mainboard.
