TPS with "transformational" SB, lots of bombs

Hi everyone,

i would like to discuss this TPS-build. It is pretty much standard, only the sideboard "transforms" it into an Oath-deck. Do you think it's worth all the SB space to inprove the matchups against highly disruptive aggro-decks? I think just adding a few pyroclasms/Massacre isn't strong enough here, and the tinkered Colossus is bounceable....

I tried to regard the following points which are a fact for this kind of deck imo:

-there has to be a really high amount of bombs so that a single Duress doesn't hit you out of the game for the next 4 turns
-only the best protection
-the best acceleration with the full load of artifact acceleration, making the Storm-spells really strong
-you have to be fast and should be able to play a bomb each turn
-you should be not so much Yawg-Will-dependant and grave-dependant
-there are tons of Artifacts (Spheres...) or fast aggro with Goyfs out there preventing your win. There must be done something about this. This is where the transformational SB comes into play (Oath with hardcastable creatures). As an alternative i post a more traditional SB, which is stronger against Control, other TPS and Flash.
-there is faster combo like Ichorid or Flash out there, so find a way against these (Tinker --> Platz, Oath --> Platz, hardcast Platz, Discard)

I think lowering acceleration (you NEED acceleration to be fast enough) as it has been done in the newer "Super" Long builds is not good since you play a lot of bombs which have to pay off very fast, additional Misdirections (low blue count) have no place in this deck.
What i would really like to add is 1 more Intuition but there seems to be no place. Colossus seems to be a must since he saves your life when there is no chance forcing some spells through in a turn (seeing Chalice, Null Rod....) and can let me win through Gaddock Teeg.

I would like to read your opinions. I like this build more than the Gush-Tendrils-decks since this one doesn't rely highly on one card (Fastbond) and from my experience the deck also can win without Y. Will. I had a really funny 1st turn kill where i made 58 Goblin tokens and took 60 off his life (with a huge Mind's Desire, which is incredible in this deck). Merchant Scroll doesn't fit in this kind of deck imo.

Card discussion:

-Oath-SB: Helps against Ichorid, all fast aggro (!!)
-Trygon Predator: seems lame, but bringing this one in against Stax can save my day. I know that only bounce often is not enough to fight through the wall of artifacts. In this matchup the symmetrical draw is sided out (Wheel, Twister). Do you think this is better than Rack and Ruin/Rebuild? Trygon can also handle Pyrostatic Pillar.
-Echoing Truth (,Platz) and Thoughtseize help against control and Flash
-no Cabal Ritual: well, they are ok, but i think we shouldn't overdo it with the non-permanent acceleration
-no Recoup: there are better things out there. It is a grave-dependant card only really good with Will and we don't want needed synergies
-Fact or Fiction is questionable. An Intuition would be more controllable, acts like Gifts and is faster
