Impenetrable Belief (Yellow)

It does not matter when the cards were put into the banished zone this turn or if they were put in there at the same time as long as three have been put into the banished zone this turn. The cards also don’t need to still be in the banished zone.

If cards are put into the banished zone that would cause Impenetrable belief to gain +2[d} after it is already defending, it would still gain the bonus as the effect is continuous and not a trigger

Impenetrable Belief can only get +2 even if more than 3 cards is banished.
