Stoneblade is apparently giving this another go. Got Richard Garfield on-board, and are stealing ideas from Keyforge and Smash Up, by having algorithmically generated half-decks that you mash together to make your actual deck. Solforge "Fusion" Kickstarter next month.
Weirdly, they want to make a Physical version, which seems arse with the whole needing to meld and then seperate deck "pods" like the Star Wars LCG did. Also, don't know how the "level up" stuff will work in a physical game, unless the deck comes with extra "leveled" copies of the cards to swap in, which seems clunky and cardboard intensive.
