When Discipline is played in a chain, when do you draw the card - immediately when played or after the chain resolves?

Ruling: You draw the card when your Discipline resolves (as the chain resolves backwards), not when it is initially played onto the chain.

Sequence:

• All Disciplines are added to the chain first
• The chain resolves backwards
• Each Discipline resolves one at a time, granting +2 and drawing a card
• After each Discipline resolves, there is a window to react with newly drawn cards

Nuances:

• You can draw a card from your Discipline resolving, then use that newly drawn card to react before the chain finishes
• You cannot react to your own Discipline with the card you drew from it, but you can react after it resolves to earlier effects in the chain
