My TPS/Mentor hybrid is something a bit like a Brian Kelly deck. I have a few singletons, like Kaya, that sort of push the boundaries of "normal TPS". I have a singleton Snapcaster for the '0' ability but I primarily just fire off the '-2' twice and then reset it with the '0'. I've got 4 Duress, 4 FoW, and 2 Mindbreak Trap so the +2 card advantage every turn is just very relevant. And occasionally, since I am a Tendrils/Necro/Bargain deck, the gain 2 life ability comes up. Not to mention it comes down off a Dark Ritual and another dual land.
I like it since the rest of my deck is kind of weak to Flusterstorm, Misstep, Mindbreak, Arcane Lab, etc. and it's nice having a Bomby threat to get around that
