first thing about this deck:
i never lost a match at beginners league last season playing it, and i won a tournament and 2 times was 3rd with using this deck most of the time.

if you exspect a mirrormatch or a golem/phoenix rush, you should take out the Momentums and add a Black Hole and add a blessing, or still a momentum (if opponent decides to go aether-lock), or a vampire dagger (he have to deflag it+arsenics too) or a basilisk blood, reverse time, many options.
it is definitly one of the greatest unupgraded pvp-decks atm, you could beat any other deck, problems are mono-entropy with lots of antimatters and golem rushes with 2 fast golems (first turn is very hard).
i post this deck now, cause i saw many, many similar decks this tourney, and it is more or less public now, but i never played a mirror at previous beginners league season.
