Emry Inspector

[Albarkhane]

After quite some time without playing Legacy, i decided to go to a small shop tournament. I checked the meta and soon found out that i needed a new deck. As i was not expecting to be able to do great results, i decided that i would brew something.
I did some tests and finally ended with the list below. As expected, results at the tournament were not good but the deck shown some nice potential. I am trying now to improve it and would gladly welcome advice and hints. I don't plan to obtain a tier 1 deck but something decent enough for tournament would be great.

Here are some explanations :
- The mana base : i don't like much the 12-posts mana base so i ended using steel stompy mana base. i did not play enough games to be really sure but i may need 1-2 more mana source (i mulliganed a lot for mana).
- The prison package is quite classic and need no explanation
- Etherium sculptor/foundry inspector : after some tests i found that the lower mana cost of sculptor was better than the higher body is inspector (i almost never used it as a beater). Those slots are a blast and let me steal many games.
- Esperzoa : i felt that some flying creature were needed. i would love to play more of them but their drawback make that quite difficult.
- Master of Etherium : our Tarmo and he is usually bigger.
- Golem : a good beater with more sphere effect. If he hits the field early enough, it is game.
- Masticore : a metagame call against Planewalker. I find it to be quite good even when no planewalker.
- Canonist : a metagame call against combo that could go to sideboard but i quite like it MD.
- Emry : our broken plan for the long run.
- Swords/ratchet bomb : i needed some disruption. My first try was ratchet bomb but i was not overly fond of the results so i ended with swords that is not very good with chalice @1. I am not happy with those slots and looking for better cards there ?
- the Sideboard : should be improved, that is just a raw one.

How do you think i can improve it (if it is worth it) ?
