All wilds would be nice!!
If they go with my suggestion to include a pts based system for using the newer decks, I'd definitely be looking to purchase new cards. Only IF it's all going to be WILD. Otherwise, I'm strongly against making any moves/purchases that would further devalue my ABUCL deck.
I think we do quite well with GF frays, but anything modern (R & Ca) only would screw us up quite a bit, and we'd need to have a meeting to see who can upgrade and swap frays.
