>>23583387Primal Clash Whiscash (the non-AT one) and pic related, off the top of my head. There might be one more I'm forgetting (this is just in Standard, mind - I'm sure there were more in past formats).
It's probably the low damage and the fact that the latter is a Stage 2 that's holding the strategy back, but the effect has some seriously disruptive potential. I might just try and build around one or the other, actually.
