TL;DR - Plonk down tree. Tree has flies. Feed flies to your amazing birdo friends. Give your birds some redbull then make the corporation too broke to do anything.

What do?

Mulligan for Tree and some card draw. There is a lot of economy so you will find that anyway. Start building your rig. The key cards are obviously your birds and all resources that tax the corp to rez ice. Normally, you want to install Mayfly to tutor for your birds for cheap while also running and stealing agendas from the remote if the corp gets too comfortable. Early Beth is also good since our focus is mostly on building our rig so the corp would have a lot of credits, often giving you an extra click.

Keep a constant stream of resource economy going on by using world tree to trash an almost empty resource for a fresh one while installing bit by bit of your rig. Once you have at least Xanadu and Cortez going, you can start running consistently with your birds. Try to have at least one turbine down before you run or it is going to become too expensive. You definitely want a 2nd turbine eventually as that allows you to derez most ice for 4 to 6 credits.

Once you're setup, it is impossible for the corp to keep you out, so much so that after a couple rezzes of ice, they will run out of gas and will be left unable to rez. Plus we just derezzed whatever they rezzed. They will be clicking for credits for a turn to only rez a puny ice on our next run then click for credits again because not a single ice will remain rezzed. After that, it is simply a matter of digging R&D, often without encountering any ice because we guzzled the corp's credits.

The obvious choice for DJ Fenris is Reina but you can also use Los if you so desire. Obviously you don't want to derez stavkas, anemones, tsarevnas and some such but most others are safe to derez. Especially derez Border Control. The bigger the ice, the more pain it gives the corp, especially once they see it get derezzed immediately. Most ice costing almost double to rez on a good day too!

I read it and tossed it into the paper shredder, next!

It might be a beast, might be a man, I simply do not care because it ceases to exist.
