I should make it clear that N for the cost of Dive is adjusted immediately after Dive is used.
Every combo I can think of so far feels balanced. I've spent about 25 minutes just now going through all the combos I could think of that might be overpowered, and they all work better going a different route (usually be just having 6 of them or using fractal). Poison is way too expensive compared to having 6 Chrysaoras and improved poisons, growth costs a lot compared to growing multiple creatuers/playing more cards, etc. etc.
Thanks. I thought of the card when I saw Rustler/Leaf Dragon's ability but knew there was no way it would be fair without increasing the ability cost. It should be like any ideal card, viable, but not always the best option.
With SoR, I realized this could easily be a Shard, and a few days ago I put together a cohesive thought, and then saw the contest and figured, "Why the hell not?"
The only major problems were "Alacrity" not being on the list and "Industriousness" losing the last 's' in planplan's generator.
