I am also toying to the idea of fitting 2 mentors (I own just 2 mentors) in the bomberman build. It would be something similar to this

Scenario A : no confidantsWithout confidants, I'd orient the deck towards more combo and less control. So -4 confidants, -1 drain, -1 swords, +2 mentors to start
+3 Probes, +1 repeal sound nice in my head. If I follow that way I'd like to play more snapcasters. And maybe that random magus of the future.
Y.will maybe? Vampiric? Mystical? Then I'd like to play tinker, but not sure about the robot.
Other option is to take black (nihil and demonic out), improving the manabase a little. Then I would fit a merchant scroll and then maybe a hurkyl's (merchant to add another shuffle effect, really welcome with sensei). Hurkyl's is great against mud, wonderful against null rod, useful with mentor, cantrip with sensei, silver bullet against random robot... and fow fodder, of course!
And without black, maybe vault+key go out. In some tournaments they have been my primary win condition (as awkward as it sounds) and key is quite nice with sensei, trinket and auriok.
DTT was never impressive. I tried FOF or gifts also, probably gifts being the best of them (but my lack of skill makes FOF more attractive to me). Nevertheless without drains they are not so good, but I'm quite bad as control player, and I just own 1 drain (I could probably borrow some).
Another random idea is to fit gushes. Random idea, I don't like too much, but mentor could use that free spell. The more I think, the more I dislike.
Tezzeret? Really, tezzeret? Without drains? Well, it's a bomb on it's own and fetches for lotus. Not worst card in the world.
Tezzeret 2.0? If I drop vault, tezz 2 is probably better, but makes me stay on black. Wonderful with sensei, complements with mentor for a quick aggro win.
Scenario B: confidants In this scenario I'd like to go to 4 caverns. Confidant and mentor work nice since confidant provides fodder to mentor, but creatures do not trigger mentor, so I cannot overload. In this path creature sweepers and target removal improve a lot against me. I lose explosiveness. On the other hand, I can make a small transformation to more humans after SB, but would demand major changes on the deck, starting from mana configuration and maybe taking out auriok combo. Unless I get hit in my head, I won't do this.
