imperial iron wall is a important side deck card now?

archetype that useful against included:

infernoid(top 1 total 90 %(except decatron) shut down)
kozmo(man, kozmo second effect....)
ritual beast(no contact fusion......)
nekroz(not very useful but still can affect i guess)

so can imperial iron wall worth for that one of your 15 cards space?

infernoid player dont feel sad, you can side card like mst, twister and trap eater too^^

Imperial wall is certainly a useful side, probably doesn't effect the current meta all that much but non the less still useful

I personally have it in my side deck, because I feel it's becoming an important card, with Ritual Beasts, Kozmo and Nekroz all being a thing.

cough cough lanceas better js

It's only for 1 turn, so I prefer iron wall.

i think IIW is great i side 3 game winner against some decks XD

Exactly, I've been up against Kozmo a bit recently and I sided in 3 and they just could not function, and I ran them over. Same with Ritual Beast, though I haven't seen Nekroz much at the moment.
