Exchange (換装 ; kansou) is a keyword introduced in SD52, exclusive to "Strike Gundam"-named Spirit cards from the Gundam Seed series. The wording is as follows:
- Exchange: - When your "Strike Gundam" Spirit attacks/blocks, this card in your Hand can change places in refreshed position with it. "Exchange" can only be used once per turn.
