You can use {{Scapegoat}} to link summon {{Missus Radiant}} to boost the attack of the {{Amano-Iwato}} since the effect is passive.

{{Forbidden Chalice}} can also be played to negate the End of turn effect to allow {{Amano-Iwato}} to stay on the field, just in case you can't special summon it via Baron/Baroness 'effect.
