I'm not sure whether it will take off as viable strategy in competitive playing. In Turf War it can be a strong opening move to get one of your players on the enemy's side, but as in ranked modes the gates close immediately after the game starts, I don't think it will become something everyone has to learn.
In regard of the difficulty it reminds me of a Mario Kart gltich - easy to hit once, but very hard to hit consistently.
