From where I learned about this deck, the best pilot of it I know uses 3 different GPs depending on which God you face. For Nature, Lysander's is great because it renders their 1/4 and 1/3s useless. Against War, the healing is great for when you've gained board control to stay alive from their Slayer. Acolyte is great against Magic for sure, but try to play around with the GP next time. Granted I only got 14 wins in the last two weekends with a similar deck (without the Canonize and PWs and Sern).
Against nature, I nearly always want extra bodies given their random removal and confused creatures. Paying 2 mana to make their 1 mana creature 0 strength seems really bad. They could still get hit with wildfire for example. I'll think on it, though!
But you didn't spend a card to "remove" it, plus you can Infiltrator them later if you wanted. If they Wildfire just hit them again with it after. The best feeling is using Lysander's on a Guild Enforcer and then Light's Levying it haha, not that Nature plays GE much but against Deception or Death.
I get your reasons though, it's hard to really evaluate which GP is actually better but it's fun and has worked for me (and that guy)
