The primer shows a decent structure of how I value each card (I tried to show the most valuable at the top, descending to the least valuable). Perhaps I should say that more explicitly in the primer. The generic answer is at the bottom of that list. Ornithopter, Myr Enforcer, Workers, and sometimes Frogmites are the cards I side out. It depends on the match and how many cards I need to side in. Examples:
If I'm playing against certain control decks, Ornithopters flying is less valuable, and so I'm often inclined to remove them for gamebreakers like Krosan Grip.
If I'm facing Deed, then I never take out Myr Enforcers.
I have dropped 1-2 MoE against copious amounts of mana denial, but I'm not convinced that is the correct play. If I had a 4th Vial in the main, I certainly wouldn't do this.
If I'm only siding Pithing Needles, it often substitutes for the Workers.
