Edison-Accurate PSCT:
Target 1 face-up monster on the field; its original ATK becomes half of its printed ATK until the End Phase.
Show/Hide Modern PSCTEdison Rulings:
● Shrink sets the ATK equal to half the target's original ATK, after which other modifiers are applied. Applying a second "Shrink" will not halve the ATK again.
● VS "Card Trooper"/"Exarion Universe" (ATK/DEF increase/decrease applying only to itself):
Half its original ATK, then reapply the ATK/DEF increase/decrease from its effect.
(The UDE ruling does not apply to Edison)
● VS "Blackwing - Sirocco the Dawn"/"Rush Recklessly" (ATK/DEF increase/decrease, can apply to other cards):
Half the original ATK, then reapply the ATK/DEF increase/decrease from the effect.
● VS "Tragoedia" (0 original ATK, gains ATK):
Shrink has no effect (0 is halved to 0, then it immediately regains its ATK for each card in hand).
● VS "Chimeratech Fortress Dragon" (ATK is set once it is summoned):
Chimeratech's ATK becomes 0 permanently.
● VS "Gren Maju Da Eiza" (original ATK becomes a value):
Halve its ATK. If the number of banished cards changes, it becomes halved based off of that new value.
● VS Equip Spell Cards:
Halve the original ATK, then apply any changes from the Equip Spell Cards.
