my opponent makes a rescue attempt against me. i give them 1/2 of the lost souls card, playing burial the other half. however, my opponent at the same time attempts to play their son of god on the other 1/2, but since i have first response to my own action, i figure i am allowed to bury my own lost souls. however, there are other lost souls available for the son of god to rescue. is the player that played son of god allowed to take son of god back into their hand, or does the card stick since it was played and there are other targets available for it to rescue?
