Tribute 1 face-up monster on either side of the field: Its controller can Special Summon 1 monster from their hand or Deck with the same Type and Attribute and an ATK or DEF greater than the tributed card. Card effects cannot be activated for the rest of this turn, except for the effects of a monster Special Summoned by this card. You can only activate 1 "Power Creep" per turn.
Spent a while trying to come up with an effect for the image. If you have any more fitting ideas, let me know.
