(This card is always treated as a Rescue-ACE card.)
If you control a Rescue-ACE monster: Target 1 Effect Monster your opponent controls; this turn, that Effect Monster cannot attack, also its effects are negated. If you control Rescue-ACE Hydrant at resolution of this effect, that monster also cannot be used as material for a Fusion, Synchro, Xyz, or Link Summon this turn.
