503.12.

An effect that instructs a player to "play a copy" of an object follows the rules for playing spells and abilities, except that the copy is played while another spell or ability is resolving. Playing a copy of a nonland object follows steps 409.1a-409.1h of rule 409, "Playing Spells and Activated Abilities," then the copy becomes played. The played copy is a spell on the stack, and just like any other spell it can resolve or be countered.
