Anusien,
I have never found Strip Mine to be that great in this deck, as I almost always wish it were a colored mana. This is the same reason for recently cutting Library, as right now in the format, the first three turns seem all important for Bomberman to survive. This normally means that Library is weaker. This plus the addition of Stax back into the metagame in force due to multiple sphere effects has lead to be eschewing non-basics in favor of basics for a while now. Time will tell, if that is wise.
Academy is possibly slightly more relevant because it can get you to three mana more quickly, plus with the number of artifacts in the deck, it is at least an island and normally counts for 2 or 3

when it is in play.
Arbiter isn't always cheap enough, but I see it in a similar vein to some of the bombs that various combo decks run. If it can be cast early (often by turn 2 or 3) especially of of an early Trinket Mage for Lotus, it can be backbreaking. Often it is a must counter in the GAT matchup as it screws up their mana, especially if they are mana light.
I have very rarely had a problem with mana crypt, although on occasion I have had to explosives on zero to ensure safety from crypt. The dreadnoughts certainly make racing crypt easier, although in previous builds with Cunning Wish, wishing for a bounce spell also helps. All in all, I think it is a necessary evil, as it ramps up your mana substantially.
In terms of sideboard, I have never been fond of playing Leyline of the Void in decks I cannot cast it in, and I have found the samurai to be a good substitute. Needless to say they are as relevant in the flash matchup as Leyline, except that many flash players have boarded expecting leylines not a creature answer. In terms of Ichorid, it not only neuters their Ichorid recurring, which admittedly is less useful that it once was; but also stops all bridge activations too (nothing goes to the graveyard). This neuters almost all of Ichorid's relevant plays whilst leaving you with a functional 3/3 for blocking any 2/2 they have in play. It may not be the best play, but I was only expecting a few Ichorid decks and feel it bridges the gap between too much hate, and not enough. Finally there are certain times when i play against someone who has played against enough to know I am playing Bomberman. In these instances it is sometimes useful to board out the Auriok Salvagers and bring in other creatures and play in a vein akin to UW fish. The samurai are also useful to a small degree against fish decks where they trade favorably and remove their strip effects permanently in case of recursion.
Finally, in regards to the Stax package, I was previously running Energy Flux in the board. However, many Stax players in the NE are now playing Eon Hubs in their boards as an answer to this and somewhat to answer Ichorid, as well as hurting Oath. No upkeep means no Flux trigger. As well as this I have often found that the better Workshop players know which artifacts to keep around and still soft lock me enough with Energy Flux down before they draw an answer. In lieu of this I have been playing with Rebuilds and Hurkyl's recall to allow for end of turn bouncing of permanents. This then allows for me to drop a number of threats the following turn and potentially counter the recast threats on my opponents turn. The seals were a late addition, as I had in the previous tournament faced 4 or 5 Workshop variants over 6 rounds and top 8 and top 4 where I lost. I had been going to play Aura of Silence instead, but was unsure of the double white against decks that run stip effects. I still think Aura of Silence is slighly better as, the increased manacost of their artifacts and enchantments severely hinders them unless they get multiple shops out.
Thanks for your response, and I'm glad you have found my rambling useful. if we can just get some of the Canadians to comment on Bomberman, we may be able to get a better discourse going as they have shown themselves to be very proficient with it both at home and when visiting for big events here.
