Ill be testing it in Henzie
Getting there is a lot easier than it seems, thanks to Eldrazi Temple and Ugins Labyrinth which get you there a lot faster
Even if you weren't immediately boosted in this way, Nissa would still be pretty tricky to deal with, as she turns your lands into vigilant creatures that can attack and then block, right away
Although some iterations of this build like to get ahead with some early aggression Wargear offers too much blowout potential to be of much help in those more attacking builds
So, a quick analysis: for 1 mana, you can put this card into play, and it can be tapped to gain CC (two colorless mana)
Most things get easier with that enchantment, to be fair
