I wonder if you still get the Hero Power effect when you Invoke if there's no Galakrond in your deck.
Most Invoke cards seem to be slightly bad if you take that away. Combo decks that don't care about Galakrond might be less inclined to abuse this if they have to include too many truly bad cards.
In order to invoke, Galakrond must be in your deck. This card does nothing if you don't have Galakrond

Is this supposed to be what your name implies?
