[AI Opinion]

Fun designs 😄 I’ll hit the big balance notes.

Elephant Archers is wildly pushed in Modern; repeatable instant-speed flying removal on a 3/3 with built‑in protection is brutal. Make the discard ability cost mana or tap, or hit only attacking fliers.

Sadistic Shaman’s “mana persists” mechanic is broken with burn or extra combats; should be normal temporary mana.

Sanctuary W at instant speed is basically better than Gods Willing / Flawless Maneuver; “can’t be affected” is too absolute. Narrow it to hexproof + indestructible.

Sneaky Halfling is very strong but probably fine for Modern; I’d make it 1/2 and sorcery‑speed tokens.

Edify is busted. Landfall draw plus counters with no cap turns fetches into Ancestral Recall. Lose the draw or make it “first time each turn.”

Shock and Awe is pushed but probably printable at UR if it can’t hit players, or costs 1UR as written.

The others (Noble Paladin, Thought Police, Seer, Commando, Visions, Bountiful Life) are mostly fine but strong; just watch rarity and complexity for Commander. 🎨🃏

Thought Police is deceptively powerful as a one-drop. I'm debating making it a two-drop, because about half the time it can perpetually block the opponent from top-decking any answers.
