Both players get to see the card picked up for “Conscription”.
If your Monster Card Zones are full, you can activate “Conscription”, and if you pick up a monster you can Normal Summon, it is destroyed and sent to the Graveyard.
If you pick up a Spirit Monster, it cannot be Special Summoned so it is added to your opponent’s hand.
If you pick up “Rare Metal Dragon” for “Conscription”, it is added to your opponent’s hand.
If you cannot Summon because you activated “Scapegoat” or “Stray Lambs” that turn, you cannot activate “Conscription”.
You can use “Royal Oppression” to negate the Special Summon of “Conscription”.
