What's the nastiest ICE you can hit a runner with using Aginfusion? Probably Excalibur, if you aren't going for a flatline. This is a rush deck that can go glacier if it needs to, but you have to actually bother to position your ice to win.
First order of business is either scoring a Nisei if you have a window, or getting an Excalibur rezzed somewhere. Ideally it's either on archives or a remote, but it MUST be positioned outermost. Our scoring server wants Chimera as the innermost ice. This is important because it's a gearcheck to help rush a Nisei Mk 2 early, and it is derezzed later to use with AgInfusion's ability. Late game we want the runner to have to pay through a taxing server and use the AgInfusion ability only when needed, so as to maximize how much the runner has to pay to steal from the remote.
If the runner can break Excalibur you usually want to run them into your AI hate instead. You can get runners to set up that remote for you by playing neveradvance with your Braintrusts/Campaigns.
This isn't tested much at all, but it's a lot of fun and didn't drop a game during an admittedly casual meet up. Of note, the single Sunset that I added as a joke was the card that allowed me to win an incredible game against a Dedicated Egret Yog Kit, which a positional Jinteki deck has no right to win. :P
Been testing an asset spam version of this with team sponsorship/Executive boot to help keep the ice up on vital servers. Not sure it's viable, but it is interesting.
Being able to have an excalibur and a cobra + batty rezed and know you've got a window is pretty nuts, and fi they try to bounce off it to at least force the ice trash you still get to reinstall with sponsorship on the score. Probably still needs tweaking but might be worth looking into.
