The Mindskinner + Body of Research

Prerequisites

An opponent cannot block creatures you control.

Steps

1. Cast Body of Research by paying {G}{G}{G}{U}{U}{U}, creating a 0/0 Fractal creature token, then putting a number of +1/+1 counters on it equal to your deck size.
2. Optionally, give the Fractal token haste, or proceed to your next turn.
3. Declare the Fractal and The Mindskinner, if desired/able, as attackers.
4. When the Fractal, and The Mindskinner if it attacked, would deal combat damage to the opponent, The Mindskinner prevents that damage, and causes each opponent to mill that many cards.
