You got 2 healing per round. In the second round you got 4 heal for 4 ER (this is 2 First Aids), and on the start of the third round after you play this card you exceed this. The more you stay in the game, the more Healing Factor is useful. Only downside is cost 3, which is pretty high... but you can calculate this.

Overall rating (A-C) A One of the few Pool cards, that you can always consider and have not really downsides
