For the most part, Vengevine answers those problem cards. I'm mostly concerned with the Turn 2 Stoneforge Mystic -> Jitte draw; which appears to happen every time (that is to say, this line of play is very consistent for X & Taxes decks). Needle of Wirewood Symbiote is an annoyance, but mostly Canonist EOT and Equipment is the primary need for KGrips, aside from trouble enchantments.
