Do conditional passive abilities apply mid-resolution of a spell/ability, or only during the next cleanup?

Ruling: Passive abilities check constantly, including during the resolution of spells and abilities.

Sequence:

• When a spell begins resolving that changes game state (like drawing cards)
• Passive abilities immediately recognize those state changes
• The passive ability applies before the spell finishes resolving

Nuances:

• In the first example (Draw 2, Deal 1 damage to all units), the unit gains +1 Might from drawing cards before damage is dealt, so it survives with 2 Might
• In the second example (Draw 2, Kill all units with 1 or less Might), the unit gains +1 Might from drawing cards before the kill effect checks, so it survives with 2 Might
• There was initially no direct rule in the CRD addressing this, but it was confirmed that passive abilities check constantly
