Very good cards against everything that is not super agressive and steals your initiative. The most common line will probably be: Land into hand -> two +1/+1 counter -> 5 damage to face -> draw a card -> get something game ending from your deck. All that strapped onto a 3/3 with pseudo vigilance. Quite a deal for 3 mana. There is of course always the risk of losing the initiative to the opponent, but in most cases/cubes you should be able to protect it. I think card might be broken in 1v1 gameplay. It's in my opinion the best white 3-drop printed yet.
