Activate the effect of "Junk Anchor" by targeting "Junk Forward" in your Graveyard, and discarding "Limiter Overload" from your hand.

Then, Synchro Summon "Junk Warrior." The effect of "Junk Warrior" will activate upon Synchro Summon, and the effect of "Limiter Overload" will chain to it.

Since the effect of "Speed Warrior" resolves first, "Junk Warrior" will have 3200 ATK!
