Unless you already have 3 MM shards, and just need a 4th to make an UR MM to evolve a summons UR unleasher or other great card, I'd go with the SR MM this time.

Red Eye is a really useful card, and you'll find two eventual GUR unleashers will make a big difference to your teams. As for left over rings, I'd use them to buy arcana or jewels to help you awaken the Red Eyes.

I think you'd be better off having a second Red Eye that you can use, than a MM shard that may sit waiting 3 more months before it can be amalgated.
