@NQN - black splash and no Vindicate? What's the plan against Planeswalkers?

The black splash expresses its power in 3 ways, first it gives you access to Vindicate which is the strongest single card removal in the game, second it gives you access to EE@3, and finally it gives you access to Extirpate and maybe Diabolic Edict in the wish board. I just don't see opening yourself up to extra non-basic hate unless you are getting the best bang out of the transaction.
