Oracle Text
Permanents you control gain hexproof and indestructible until end of turn.
Card Rulings
2/9/2017 The set of permanents affected by Heroic Intervention is determined as the spell resolves. Permanents you begin to control later in the turn won’t gain hexproof and indestructible.
It could really mean that regeneration is once and for all been substituted by indestructibility effects.
Can someone tell me why this isn't white?
