Treasure Map can be good if you plan on using more than 1 copy of Hey, Trunade! as well as other cards that can return set spell/trap cards to your hand like Tornado Bird. Tornado Bird can be good if you use continuous spell/trap cards like Mirror Wall. Use it when your opponent attacks and return it to your hand so you won't have to pay the cost and be able to use it again later.
Since it will also return your own spell and trap cards, it works best when you use quick-play cards that can benefit when you set them and can be activated from your hand during your turn. Enemy Controller can be good in most situations, but it's a dead card against monsters that can't be targeted like toons or hazy monsters, while Super Rush is good against decks with the same monster attributes, but won't do well against diverse ones.
The limitation of this card only confirms that konami love cancer decks, people played this thanks to cards like wall of d, and the new mirror force, but it seems that konami prefer cancer that decks with real strategy
You can only activate impenetrable attack in the battle phase. So activating hey trunade in the main phase will always send it back to the hand. Hey trunade will always send back wall of disruption, draining shield, impenetrable attack, and widespread ruin. They can sent back canadia, e-con, and floodgate if they can’t chain them to your monsters.
