They recently changed Olgierd from "Olgierd's power cannot be changed by other cards
wherever he is." to "This card's power cannot be changed by other cards or abilities." so it could be intended since he now also can receive boost from Handbuff* while in hand and probably also while in Deck (NR Erland Dandelion) by making his skill only work while he's on the Board.
*Tried it after they changed him
