A Few Mage Cycles

I am looking for new ideas to build decks with. There have been several mage cycles. Here are the ones I have dug up. I am sure I am missing a cycle or two. For now, this is just a place holder to know where to look for these.

Mirage had a shard cycle. All are one-drops.

The original Ravnica had ten guild mages. All of these are two-drop hybrids.

Shards of Alara remade the Mirage mages. All of these are three-drops.

And Return to Ravnica has another cycle of guild mages. We are back to two-drops, although these are harder to cast than the hybrids from the original Ravnica block.
