If i have forebear's blade attached to my rekindling phoenix and the Phoenix dies. Does the elemental token get created fast enough for the forebear's blade to target and attach to the elemental token?
No. Forebear's Blade and Rekindling Phoenix trigger at the same time. You put the triggers on the stack in whatever order you want, choosing a target for Blade as it placed on the stack. Since Phoenix's ability is still on the stack, there is no Elemental token to target. If there is no legal target to choose, Blade's ability is removed from the stack.
