Barroom Revelry

Kicker — {1}{w}, Discard a card. (You may pay {1}{w} and discard a card in addition to any other costs as you cast this spell.)
Target creature you control gets +2/+0 until end of turn. If it was kicked, that creature gains lifelink until end of turn.
In the heat of the moment, the bar's patrons find courage in a shared toast.
