T2
Paradox Engine
into T3 victory using
Isochron Scepter
with a flicker imprinted, and finish with an infinite loop of flickering a
Skymarch Bloodletter
for ETB opponent life loss and self life gain.
Assuming a good opening hand and first draws includes Swamp, Tomb, Engine, Ring, Scepter, bloodletter, and a flicker.
T1:
swamp, sol ring
t2:
ancient tomb (-2 life), paradox engine
t3:
any land, play isochron w/flicker imprinted using sol ring (engine untaps sol ring), skymarch bloodletter using swamp and this turn's land and ring (engine untaps ring, opponent takes 2 etb life from bloodletter), pay for isochron's flicker w/ring & use flicker on bloodletter (engine untaps ring and scepter, opponent takes 2 etb life from bloodletter) repeat to win.

Alternative strats: imprint tutor to get engine/flicker/bloodletter/scepter/counterspell. slows deck down by a turn or two, but should be recoverable. Could also tutor Bolas and mountain/island to flicker bolas for complete hand control via discard ETB effect of Bolas. Possibly swap out for some dual color lands (Shock lands?) to make this easier.
Theorycrafted deck based on interaction between
Isochron Scepter
and
Paradox Engine
for casual/vintage play.
