Assault Formation’s first ability doesn’t actually change any creature’s power. It changes only the amount of combat damage it assigns. All other rules and effects that check power or toughness use the real values. For example, Hunt the Weak won’t cause a creature to fight with its toughness.

For example, a 2/3 creature will assign 3 combat damage rather than 2.
