Brainsurge - Modern Horizons 3: Extras (Uncommon) [XMH3-399]

Brainsurge allows you to draw four cards and then rearrange two cards from your hand back on top of your library. This can help you dig for key cards while setting up your next draw, making it effective in control and combo decks that rely on specific sequences. However, the cost of {2}{U} means it may not fit into fast-paced strategies that require quick plays.
