The 3 combo pieces

• Harmless Offering
• Knowledge Pool
• Moderation

How to execute it

1. Cast Harmless Offering by paying {2}{R}, giving control of Moderation to an opponent.
2. Cast Knowledge Pool by paying {6}.
3. Whenever the opponent that controls Moderation casts a spell from their hand, Knowledge Pool triggers, exiling that spell.
4. Because Moderation prevents the opponent from casting more than one spell each turn, the opponent cannot cast the spell permitted by Knowledge Pool, or any other spell that turn.

What the combo produces

• Exile all spells target opponent casts from their hand
• Lock
• Target opponent can only cast one spell per turn
