Metal Restraint Made Raised Shield

Metal Restraint Made Raised Shield After this card's activation, it remains on the field. These effects apply to monsters once even if similar effects are active: •When this card is activated: All current changes to monsters' ATK from activated effects previously applied are applied to those monsters' DEF instead, and vice versa. •While this card is face-up, "Metal Restraint" monsters that are unaffected by their controller's cards' effects and can't be targeted or equipped by them apply this effect to their controller's opponent's cards instead, also the original ATK and DEF of face-up monsters are switched, and changes to their ATK from cards/effects activated and/or continuously applied while this card is face-up are applied to their DEF instead, and vice versa.
 * Trap/Normal

Once during your opponent's Endphase, if you do not control a "Metal Restraint" monster: Destroy this card. During your opponent's turn, if you control a "Metal Restraint" monster, you can activate this card in the GY if it was sent there by its own effect, but if you do, banish it when it leaves the field.

To Fix
When activated effect and continuous-like effect - wording fails to capture effects being statically applied but not on the field, like Phantom Beast Cross-Wing.
