Harmless Offering
1

   Prerequisites

What do I need to start this combo?
Harmless Offering in hand.
Knowledge Pool and Colfenor's Plans on the battlefield.
2 available

   Steps

How does this combo work?
1
Cast Harmless Offering by paying 2, giving control of Colfenor's Plans to an opponent.
2
Whenever the opponent that controls Colfenor's Plans casts a spell from their hand, Knowledge Pool triggers, exiling that spell.
3
Because Colfenor's Plans 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.

   Results

What do I get from this combo?
Exile all spells cast from target opponent's hand
Target opponent can only cast one spell per turn
Target opponent skips their draw step
