If a monster you control would be used as Link Material for an "S-Force" monster, this card in your hand can also be used as material. During the Main Phase (Quick Effect): You can return this card to the hand, and if you do, Special Summon 1 Level 2 or higher "S-Force" monster from your hand. If an "S-Force" monster you control would banish a card(s) from your hand to activate its effect, you can banish this card from your GY instead. You can only use each effect of "S-Force Retroactive" once per turn.
