Repeating Spells

Would it be possible to give these spells a small minimum number of casts higher than 1? It really sucks spending your turn on a spell like Murder of Crows and it to instantly end after the first hit. I know spells are generally on the strong side right now, but the random-target repeating spells are in the “feel bad to use” area. 2 or 3 minimum hits (maybe an extra for Cloudbeam since it has a higher cost and lower chance to stop) would ease up on those moments without making the spells broken, most likely.
