If Scrap Recycler is Special Summoned by Giant Rat, does its effect activate, or can it miss timing?✓
Giant Rat is destroyed and Special Summons Scrap Recycler.
It will activate if Giant Rat is Chain Link 1. If Giant Rat's effect is Chain Link 2 or higher, Scrap Recycler can miss timing because it is a 'when... you can' effect.
Can Royal Oppression be used on recruiters like Giant Rat?!
Giant Rat is destroyed in battle and its effect would activate.
No. Recruiter effects activate in the Damage Step, and Oppression cannot be used during the Damage Step.

● This effect activates in the Damage Step, so it can never be negated by "Royal Oppression".
Cards like "Bottomless Trap Hole" and "Torrential Tribute" can never be used in response to this Summon.

If you attack with your "Giant Rat" and it is destroyed as a result of battle, you may attack with the monster Special Summoned by "Giant Rat" before entering Main Phase 2.
If your opponent controls your "Giant Rat" and it is destroyed as a result of battle, you get the effect of "Giant Rat" NOT your opponent.
Since the Special Summoning occurs during the Damage Step, "Torrential Tribute", etc. cannot be used.
