The List

In a twinkling the table was laid. There was hot soup, cold meats, a blackberry tart, new loaves, slabs of butter, and half a ripe cheese: good plain food, as good as the Shire could show.

Tales of Middle-earth Commander

Starter Commander Decks

Apply power bonuses from counters the creature enters the battlefield with and continuous effects such as that of Valiant Knight before checking to see if Mentor of the Meek's ability will trigger.

Mentor of the Meek's ability checks the power of the other creature only as it enters the battlefield. If that creature's power is 2 or less, the ability will trigger. Once the ability triggers, raising that creature's power above 2 won't affect that ability. Similarly, reducing the creature's power to 2 or less after it enters the battlefield won't cause the ability to trigger.

While resolving the triggered ability of Mentor of the Meek, you can't pay {1} multiple times to draw more than one card.
