If you're going for the quick stab, why not 3 kiln/0 Dryad?
Have you considered Reckless Charge?
Regardless of whether you go with a more aggressive strategy or not, you're probably going to want more mental misstep to deflect removal.
Because Vintage has super variance. I have considered R-Haste, but what would you cut? I had 3 Mental Misstep in the original build, but it got copoed over w/ Standard Delver so I'm not sure what I had them over. Either way; Delver is here to stay
