Well, I don't really understand Destiny Heros on the actual format but, Miracle's Wake couldn't be replaced by Call of the Haunted? You really need ALL these Destiny Heros? the deck is at 45, and cards like, Dunker, Dreadmaster without clock, idk, I feel like if it was there just because "Destiny Hero" is written on the card, just because it is a destiny hero deck you don't need to put every single destiny hero on it.

Polymerization is kinda costy now, also i'd say, replace E - Emergency Call to "Reinforcement of the Army" it is, if you have no more room on your deck, I'd run 2 Emergency Call and 1 Reinforcement on -almost- any hero deck, but if you are going to use only 1, Reinforcement is better, since it can bring any elemental hero and any destiny hero too.

Replacing some of the destiny heros by Duality/Emergency Call/ROTA, and making the deck a 40 cards deck, would increase the concistency, basically, make it less lucky reliant.

Phoenix Enforcer? Well, do as you wish, it's not such a great thing not to be destroyed by battle actually, just seeing how spirit reaper don't last so long on the field most of the times, however, I guess you could use it anyway if you wanna, but The Shining diserve a place in a deck with Miracle Fusion, also you could easyly use 3 miracle fusion on this deck.

Photon Trasher would help you to get to rank 4 monsters.

Noble Knight Gawayn... with Sparkman... well, don't really diserve a place on this deck, unless you put E-Hero Neos Alius on it.

Well, good luck with the deck.
