- Placing 1 D Counter onto D - Formation does not start a Chain.
- The second effect of D - Formation starts a Chain. It does not target.
- You cannot activate D-Formation's second effect when you Special Summon a monster face-down.
- If an effect is chained that flips the Normal or Special Summoned monster face-down, D-Formation's effect disappears.
- If you have 2 or more D-Formations with 2 D Counters when you Normal or Special Summon a monster, you can activate the second effect of each D-Formation.
- If a card’s effect Special Summons multiple monsters during your Main Phase, you can activate the second effect of D-Formation. In this case you will select which monster you will apply towards the effect when D-Formation's effect resolves.
