Fast effect timing

Fast effects are card activations and effects with a Spell Speed of 2 or higher, including monster Quick Effects, Quick-Play Spell Cards, and Trap Cards (which includes both activating Trap Cards, and activating the effects of things like Continuous Trap Cards).

Fast effects can be activated by either player – even during their opponent’s turn, as long as the conditions are appropriate. When both players want to activate fast effects at the same time, they are placed on a Chain.
