I don't know if you can manage this, but there is a SR Mirror Maiden available in Alliance Bingo Battle for 600 rings. It would damage the soldier count a bit, but it'll replace the Griffin you need. Just remember to max the levels and use Succession Arcana (the yellow butterfly one), then you're all set.

The Mirror Maiden is always there every month, but rings don't cumulate (unfortunately). I'd say save up for rods, and when there isn't any card you want, go crazy for the rings.

Hope that helps!
