Based off of Heroic-leader tournament deck

I'm trying to improve this deck to make it competitive for match-ups against Monoblack and U Devoltion. It does well against most standard tournament decks like Boros Burns, Esper, and Jund. But it needs some tweaking to make it perfect. I've noticed that with this deck I rarely get more than three mana, which makes Fabled Hero incredibly slow. I'm debating rotating him out to throw in either Quicken for the draw advantage or Mizzium Skin for the hexproof or Ethereal Armor for the heroic trigger... Any suggestions are helpful!

Heroic Trigger Cards:

Bioshift Can target two creatures and shift the counters if one would die, including the counter from targeting.

Hidden Strings Can target two creatures and you may untap of tap it. +Cipher copy when damage is done to opponent.

Triton Tactics Can target two creatures and you can untap both of them, give them +0/3 and heroic triggers all for 1 blue mana. Did I mention it also taps down creatures that it blocks? Or that it hard counters Anger of the Gods & Mizzium Mortars ?

Creature Combos:

Nivmagus Elemental + Hidden Strings After the ciphered spell copy has targeted two creatures you can exile the copy allowing you to get +2 counters and trigger heroic. However the copy will have no other effect.

Nivmagus Elemental + Triton Tactics + Gods Willing + Bioshift After the instant or Sorcery spell has been cast and triggered heroic, you may exile it giving 2 counters, however there still be no additional effect.

Fabled Hero + Bioshift Keep all your counters on one creature then swing with both, move them over to Fabled Hero and win the game.

Fabled Hero + Hidden Strings When Fabled Hero does double strike damage to a play you may cast 2 copies of Hidden Strings couple that with Brave the Elements and you should win the game.
