Improvising Battlemage

First strike
{2}: Reveal the top card of your library. If it's a creature card, Improvising Battlemage has +2/+0 and vigilance until the end of this turn. If it's a land card, put that card tapped onto the battlefield under your control. If it's a noncreature, nonland card, Improvising Battlemage deals two damage to target player. Activate this ability only once each turn, and only as a sorcery.
