The 3 combo pieces

• Knowledge Pool
• Moderation
• Zedruu the Greathearted

How to execute it

1. Activate Zedruu by paying {U}{R}{W}, giving control of Moderation to an opponent.
2. Whenever the opponent that controls Moderation casts a spell from their hand, Knowledge Pool triggers, exiling that spell.
3. 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
