At the beginning of combat on your turn, for each Aura and Equipment attached to Valduk, Keeper of the Flame, create a 3/1 red Elemental creature token with trample and haste. Exile those tokens at the beginning of the next end step.
Valduk counts all Auras and Equipment attached to it, not only Auras and Equipment you control.
If Valduk leaves the battlefield after its ability has triggered but before it resolves, use the number of Auras and Equipment that were last attached to it before it left the battlefield to determine how many tokens to create.
If Valduk leaves the battlefield after its ability has resolved, the tokens are still exiled at the beginning of the next end step.
