Haste
You may activate abilities of other creatures you control as though those creatures had haste.
: When you next activate an ability that isn't a mana ability this turn by spending four or more mana to activate it, copy that ability. You may choose new targets for the copy.

Dynaheir, Invoker Adept doesn't actually grant haste to creatures you control, nor does it let you attack with them as though they had haste.

Dynaheir has received an update to its Oracle text. Specifically, the delayed triggered ability doesn't trigger if you activate a mana ability that costs four or more mana to activate.
