Aetherflux Reservoir may not have the word “Storm” printed on it, but it is a Storm card. This is why the deck runs so many Shadowborn Apostle. When casting the first Shadowborn Apostle with Ripple 4, there is an 86% chance that of finding another Shadowborn Apostle in your next four cards. Importantly, Ripple says “cast,” so each Apostle that is Rippled into adds to the Storm count and triggers the second ability on Aetherflux Reservoir. I’ve yet to resolve these three cards in one turn and unsuccessfully pull all of the Apostles out of my deck. If you’re concerned about fizzling and think you can afford to wait, then wait until you draw a second Apostle before attempting the Ripple chain. That way should the first Apostle fail to find, the second one can begin the chain again.
Step 1: Cast Aetherflux Reservoir
Step 2: Cast Thrumming Stone
Step 3: Cast Shadowborn Apostle and begin the Ripple chain. Once all of the Apostles have been cast Sidisi's life total should be high enough to pay 50 life 3 times and kill all of your opponents. You don’t have to cast these cards all in the same turn, but it lowers a number of opportunities your opponents have to destroy one of your key artifacts.
