Duraludon VMAX's Skyscraper ability is clearly designed with other Single/Fusion Strike threats in mind, as well as anyone else who taps into Special Energy cards as the source of their strength
For example, Graf Rats has no problem exiling itself and a creature named Midnight Scavengers that you own and control, but if either one is a token, they won't meld and won't return to the battlefield
And since we're going to be proliferating way more in general thanks to more Phyrexians dying with Brimaz, Blight of Oreskos, I'm adding more counters to the deck, such as Everflowing Chalice which is totally cracked when you're proliferating it, or oil counters like Vat of Rebirth and Norn's Wellspring, and even some poison cards like Ichor Rats which adds a secondary win condition if we come up against pillowfort or lifegain decks
There are borderless, Through the Ages, and Surge Foil variants of each, upping the prices even further
