Probable cheating with Curse of Silence

**Describe the bug**
A.I. cast Curse of Silence targeting me on turn 1 perfectly naming Liquimetal Torque in my hand, which should be impossible given that there is zero information available at this stage of the game. It's one thing to name my commander since that's freely available information, but there is no way it could legally know to name Liquimetal Torque.

**Expected behavior**
In a commander game I would expect it to name the player's commander, or barring that, some kind of universal mana rock (Sol Ring, Arcane Signet, Talismans), or even the common removal in the opponent's colors.
