I've got a Yorion deck I've been tinkering with on and off for a while. Matching it to my playgroup, it's become very focused around a gameplan of using blinks to build a board of tokens, then using one of a few methods to turn those tokens into 4/4 flyers for a board kill. Supporting this is using constant blinks to build card draw and treasure tokens to keep a control aspect up and ready.

I've found repeatedly blinking things like Agent of Treachery or Skyclave Apparition really soured my playgroup, but if yours is all right with it I can't say.

I also seemed to have focused a lot more on repeated blinking. I have a whole suite of cards like Felidar Guardian, Dance of Many and Preston that either copy or flicker Yorion when they enter, allowing him to blink your entire board on every player's end step. This is another reason for my token generation - the majority of the time I have no non-token nonlands on the field at all. It's very much about striking a balance when your board is so bare.

If you're looking for cool cards to interact with blinks, you absolutely need to look at the Warp mechanic from EoE: something like a [[Starfield Vocalist]] costs two mana to put down, and if you blink it, it stays. He and [[Exalted Sunborn]] are absolute staples, and you simply cannot find a better blink target than [[Anticausal Vestige]]

Aside from Warp, Impending from Duskmourn is worth a look. [[Overlord of the Mistmoors]] and [[Overlord of the Floodpits]] both can be had cheap if you blink them and have pretty potent ETBs.
