This card is really, really strong. It's cheap, consistent damage, and you get three of them, and the damage over the course of the game you get from them is nuts. You're almost always going to be in Tiny hero form at some point on your turn, so even the "Tiny form" part of the cost is negligible.

These are great.

The damage is not an attack, so you can use them when stunned and they do not trigger things that happen on attack such as retaliate.

These are great for pinging off a tough status card or making sure you do exactly the amount of damage you need to an enemy.

Three of these out means in tiny form you are doing 3.damage and thwarting for 2 before you even play a card.
