Propaganda
From Doctor Who set
Propaganda
Enchantment
Creatures can't attack you unless their controller pays for each creature they control that's attacking you.
Rulings
- The payment is made during the declare attackers step at the same time you are declaring the attacker.
- If there are multiple attacks in a turn, then you have to pay for each attack.
- If there is more than one Propaganda on the battlefield, the cost is cumulative.
- Paying this cost is not an instant or any other kind of ability, it is an additional cost on the declaration of the attacker.
