My opening plan:
Turn 1: [mwcard=MW1J04]Battle Forge[/mwcard] then move and cast [mwcard=MW1J08]Hand of Bim-Shalla[/mwcard]
Turn 2/3: Deploy [mwcard=MW1Q27]Dawnbreaker Ring[/mwcard], then either summon [mwcard=MWSTX1CKC06]Guardian Angel[/mwcard] or equip [mwcard=MW1Q29]Staff of Asyra[/mwcard], move and cast [mwcard=MW1E29]Nullify[/mwcard]
Turn 4: Deploy [mwcard=MWSTX1CKQ04]Reflex Boots[/mwcard], [mwcard=MW1J09]Temple of the Dawnbreaker[/mwcard], [mwcard=MW1E01]Bear Strength[/mwcard] or maybe Melee?
Turn 4+: Make myself stronger and beat my opponent to a pulp
T1: this way your BF is in starting Zone or adjacent to that zone : not far enough if the battle takes you to the other side of the arena.
T2: Staff of Asyra too early imo, you may not be in combat yet, better to load up on dice here.
Also, you don't have the mana to do all of this :
T1 19 : BF + Bim-Shalla
T2 15+1 : Ring + Angel = 15 mana.
With just one mana left, your QC is wasted and actions are GOLD with a Priest.
Bottomline, your mana reserve is depleted and you'll now get your 9+1 mana every round, so no way are you going to cast Reflex Boots +Temple of the dawnbringer + FD Bear Strength on T3 as that would require 19 mana !
Compare to this opening :
T1 19 : Move sideways - Battle Forge in NC ( Near Centre ) - QC Enchanter's Ring
Place the BF in a position to cover most of the arena and a cheap means to reduce enchantments in mana cost.
T2 18+1: D Dawnbreaker Ring - QC Hand of Bim-Shalla in starting Zone - move into BF zone - FD (Face Down ) Bear Strength.
You now already have the potential to roll 6 dice and put a Burn counter down and look at all the mana you still have
T3 19+1 : D Gauntlets of Strength ( bringing your attack dice up to 7 ) .... the rest depending on opposition and board situation.
I also think Defenses, like Reflex Boots, are not ideal for the Priest.
If you avoid being hit, your Avenger ability doesn't trigger.
Ideally, you want the Priest to be hit, but not for a lot of damage, so it's better to add armour and Divine Protection and such.
