Are these custom MTG cards balanced for Commander or Modern?

Because of recent power creep, I think these cards are fair as they stand. What do you think?

[AI Opinion]

Fun designs 😄

Time Reverse is busted in both formats. “Skip a turn” is trivial in control or combo; a zero‑mana hard counter at instant speed is way above Force of Will / Pact.

Bandit Camp is too strong; repeatable 2/2s plus pseudo-card-advantage on a land would dominate grindy games.

Celestriad and Master’s Scroll are totally broken; cost‑reduction to 1 and repeatable triple strike with blue untap means instant combo kills.

Avenging Elephant, Miracle, Summoner, Soul of Thamasa and Salvation are closer, but Soul still needs a mana or timing restriction, and Miracle’s ability probably needs sorcery‑speed or higher activation.
