I would appreciate a change to orc regiment and pyramid, since they are one-shot cards and decks around them are very powerfull, but gateway should stay as it is. It is none of that one-shot victory cards and still needs to be played properly after it is played. It differs quite well from the other two... (And please, reduce gateway's cost, i never could actually imagine why it should be cost-inferior to one shots like this two xD)
And for wishing lagoon... we should really either remove that card or rework its effect completely if we change orc regiment and pyramid, else it would be just a specific summoner for the needed support card and with this a placeholder for the specific uncommon. This is its currently rolr anyway by the way.
And on the other side, strategies like buiilding, destruction or recources should not be keyword-bound. One shots like orc regiment were always good in stall decks, which did never rely on the horde keyword (that would be ineffective anyway), so why should this ever be made?
