In the case that you use "Mind on Air" with this card, equip her with either "Heart of Clear Water" or "Moon Mirror Shield". That way, she will be safe in battle, while your opponent will be Burned during your Standby Phases.
Here is a list of every card that allows you to look at your opponent's hand.
Even if you don't combo this card with anything, you can still use its effect to peer at your opponent's hand 1 card at a time, with the only possible downside to occur is to your opponent in the form of 700 damage, as well as possibly revealing their strategy to you so you can prepare to stop it.
If your opponent is attempting to punish you using this card, and you have little to no information on your opponent's hand or deck style, statistically speaking the choice Monster is liable to be correct as a random guess more than that of Spell or Trap. Most decks attempt to maintain a 1:1 ratio of Monster:Spell/Trap, so while a player may try to make their deck contain 50% monsters, the other 50% is likely split between Spells and Traps, so the highest percentage of cards in one's deck tend to be monsters. In addition, with the limit of one Normal Summon/Set per turn, your opponent may be waiting for future turns in order to be able to play their monsters; Spells and Traps may be Set on the field as long as there is room, and there is no limit to the number that may be played. Also, cards like "Judgment Dragon" and "Black Luster Soldier - Envoy of the Beginning" have Special Summoning requirements which may not be met at the time of your attack, and will be waiting in your opponent's hand. Also bear in mind that the prevalence of cards like "Solemn Judgment", "Solemn Warning", "Torrential Tribute", "Dark Hole", "Bottomless Trap Hole", and others make players weary about playing down powerful monsters unless there is little chance that they will meet their untimely demises. Pay attention to your opponent's playing style; if they have yet to Summon or Set a monster for a few turns, they may be running into an unlucky streak, as few players would willingly receive direct attacks with a playable monster still in hand. Monsters like "Maxx "C"" and "Battle Fader" also have powerful effects that activate from the hand, and may not be Summoned or Set so frequently. If you have returned cards to their hand, used a card like "Mind Haxorz" or "The Inexperienced Spy", or can quickly ascertain the current ratio of cards left in their deck, make an informed decision, but in a blind spot, a guess of Monster Card is likely more useful than either of the other two options.
