How does this compare to just not using shards of freedom in a Instosis?
Here are the pros, cons, and differences I thought of for this deck comparing it to Instosis without SoFr.
Pros:
Shields aren't a problem for this deck. That's enough.
Cons:
More combo cards means less deck space for extra time towers and hourglasses and maybe other stuff. So there's less flexibility in deck building.
Shards of Freedom can be destroyed/stolen.
Differences:
While the kill turn combo has six cards instead of eight the combo overall has more cards.
This deck makes you play all six of your super novas. Instosis without SoFr can either make you play four or six. The four super nova version loses to two damage reduction shields while the six super nova version doesn't.
Here are the builds for the four SN and six SN versions with explanations. This goes off topic from the deck in the original post but it's pleasant context for some things I said about the SoFr-less Instosis if you don't know about it already. Whether this is technically off topic I don't really know.
Spoiler for Instosis stuff:
So as far as I know Instosis without SoFr can be built with two different variations in the kill combo. These can be built with upped or unupped sundials.

This deck can use as few as four super novas if you want to. The downside is this deck's kill combo doesn't deal enough damage to beat false gods with shields that block at least two damage points.

This deck requires all twelve aether quantum to be used but it can kill through a diamond shield.
