Virtue of Knowledge

Abilities that apply "as [this permanent] enters the battlefield," such as choosing a number with Talion, the Kindly Lord, are also unaffected.

Virtue of Knowledge's ability doesn't copy the triggered ability; it just causes the ability to trigger an additional time. Any choices made as you put the ability onto the stack, such as modes and targets, are made separately for each instance of the ability. Any choices made on resolution, such as whether to put counters on a permanent, are also made individually.

You must still follow any timing restrictions and permissions for the permanent spell you cast from exile. Normally, you’ll be able to cast it only during your main phase while the stack is empty.
