Volatile Stormdrake is very fun but a couple things to keep in mind: It's not a may so you MUST exchange with an opponent if there are any legal targets. This means if all there is on the field is an Omnithopter you HAVE to trade your drake for it. The other caveat is the way the delayed sac trigger works. Since it says to sacrifice it at the end of your next end step but you no longer control the drake copy you cannot sac. What ends up happening is your opponent gets to keep any drake copies you create that swapped with their creature. Just keep that in mind.
I have this precon still built... it has like 2 or 3 infinite combos baked into the precon itself, commander+aether refinery+Amped raptor... just need Commander+Amped raptor to survive the the first combat phase, then you just keep swinging with tokens and commander, throw a rogue's passage or some way to make the commander unblockable for a turn
this comander can do much more with combos like: zada/beamplitter/feather + Galvanic Discharge / Harnessed Lightning, you can generate houndred energys for ~2 red mana if you running things like young pyromancer.
