Random Generator gave me Cocoon and Niblis of the Breath, which I translated thus. It's a bit weird, tapping your opponent's creatures as a cost, but I've seen weirder. Originally, I envisioned this as a green pacifism type card, with a draw back (you're giving your opponent's creature counters). But now that I've added the blue ability to better match the card with its predecessors, this thing is looking pretty might. Still useable for defense in an emergency, but I'd rather punch with the thing.

Alpha already had enough green answers to creatures, and not much in the way of gold, so I tossed this into the Workbench. I'm sure it will be better for Beta.

Amusingly, this has turned out rather reminiscent of a Dragon's Maze card (that came out just a month or so after this was designed): Krasis Incubation.
