Hinata Duel (Duel Commander) [Revisione 48]

Deck for 1v1 matches, but using the multiplayer banlist and rules.

Plan is to control the board with an iron fist to protect Hinata (only need to protect her from one opponent, instead of three!), keep the opponent's board empty, and set up for a game-winning infinite combo.

Infinite Combos: Reiterate + (Jeska's Will, Seething Song (with Hinata), or Reality Spasm (with Hinata)) - OR - Isochron Scepter + Dramatic Reversal = infinite spellcasts.
Infinite Spellcast payoff: Aetherflux Reservoir, Grapeshot, Brainfreeze, or Manaform Hellkite.
Hellkite serves as a backup wincon if I can't combo and game is slow. Make big dragons with expensive spells that have huge cost reductions from Hinata.

I need help cutting down to 100 cards.
Since protecting Hinata is everything to this deck, I have tons of interaction. I can't decide to lean more heavily into counterspells, removal, or other Hinata-protecting cards like Timely Ward (2 mana!) or blink spells (1 mana!).
Counters are more generally applicable, but removal provides better card advantage (Heliod's Intervention at X=10 costs 2 white mana lol). Protective permanents are, well, permanent. What do I cut?
