I like most of the new tarot cards (Ace of Rods being the only exception). Advantages:

• Provides +1 , which protects against encounter cards and many mystic spells replace other tests with it
• Free to play if in opening hand (mulligan increases your chance of drawing it)
• Does not conflict with existing assets with the new tarot slot
• Is not an item, so it's immune to many treacheries that target these

Disadvantages

• Second copy is a dead card, as players have only one tarot slot and it has no icons to commit
• Conflicts with other tarot cards, if the investigator has access to more than one faction at level 1+
• Ability to play this for free may motivate a player to mulligan important cards, like weapon assets
• Mystic assets are quite expensive, so 3 ressources can be too much
• Without appropriate assets, a bonus to doesn't do anything, so it can be a dead card (beside mythos protection)
