Originally released from the expansion set Cyberdark Impact in 2006, Chain Strike is a quick-play spell card.
Activate only as Chain Link 2 or higher; inflict 400 damage to your opponent times the Chain Link number of this card. You cannot activate this card if multiple cards/effects with the same name are in that Chain.
Chain Strike can only be activated as chain link 2 or higher while the other cards/effects activated in the chain have different names. However, if a player activates Chain Strike as chain link 4 and wants to activate a second Chain Strike as chain link 5, the player can activate both copies of Accumulated Fortune because the chain would not recognize multiple copies of Chain Strike in the same chain (but the player cannot activate a third Chain Strike as chain link 6). If the second copy of Chain Strike was activated as chain link 5 and both players do not want to activate anything else in the chain, the opponent would lose 2000 life points from the Chain Strike activated as chain link 5 and would lose 1600 life points from the Chain Strike activated as chain link 4.
Chain Strike does not see a lot of tournament play during the January 1, 2015 format.
