Well I've been using this deck for a very, very long time beginning with the Arena Beta and have found that its use has not faltered once yet. I've tweaked it a lot and have held off on posting it until it was finalized and I feel like it has been:

It's basically a combination of Elder Destruction 101 and T50 Destruction 101 with a bit of TADAbow splashed in. I would have added this to my ___ Destruction 101 series, but because it uses features unique to TADAbow I don't feel right with taking the credit in such a way. And it absolutely crushes Silver. It's usually able to shrug off slower Firestalls, stops Life rushes cold with Wings, breaks through Dim Shield chains with Discord/BH, and it has a pretty decent EM rate to top it all off. I've had a few occasions where I was able to grind 500 electrum in less than 6 minutes, but this is certainly not the norm.
A few possible changes:
The first version I had created used 2 Hourglasses to increase draw rate, but for the life of me I can't remember what I had removed to add that card in. It definitely needs the 3 BH and 3 Discord.
There have been times where I used a Steal instead of the Gargoyle, but this gives it much more rushing ability which is important against opponents with higher HPs. It's also useful against Firestalls on occasion by giving the AI bait to waste Lances/Bolts against (this is of course assuming its ability has been activated already).
You can try it with a Crusader instead of an Archangel, but I've personally found the Angel to be more useful for the most part.
I wouldn't advise switching the Phase Recluse for a TU because you need the Recluse + Wings combo very, very often.
It's able to grind Gold somewhat effectively, but it's much more effective against Silver.
