Galim, the Overly Honest

Double strike
At the beginning of your upkeep, you may reveal the top card of your library. If you do, gain 3 life or create Windell Jr., a legendary 3/3 white Goat creature token with vigilance and trample.
Whenever Galim, the Overly Honest attacks, reveal any number of cards at random from your hand. For each card revealed in this way, this creature gains +1/0 until the end of turn.

Galim doesn't know when to stop talking.
