I think what the OP is looking for is a way to kill via damage without being vulnerable at a certain choke-point. That is the fundamental weakness of fast combo decks: being susceptible to a single strike that dismantles the confluence of events required to develop the kill. For example, I can cast a Chalice of the Void @ 1 vs. Storm combo and pierce their entire strategy.
Right. 'Cause playing a deck with 35-40 1-drops is a great way to avoid that "piercing" CotV?
I can appreciate what desolutionist is trying to do here, and I have some respect for Elves. But it really is a fool's errand.
Vintage has never had more strongly positioned silver bullets. Recent printings have dictated that decks like BUG, Merfolk, UW and MUD have become viable (even favored?) metagame bulwarks. Sure Oath, TVK.dec and storm are viable, but there is a ton of hate and you need to be a pretty slick pilot.
This search for replicating that last strategy with creatures has already been optimized in MUD (w/Greaves) and Delver, both of which can either goldfish or stop their opponent and often both.
Caverns is good, sure. But it's a fig leaf when faced with spheres and wastelands on top of CotV.
