Wherever You Go, There You Are
With no certain future, and no purpose other than to prevail
#1-Orders From Rome-Useful if the Panzer Divisions are not yet on the board. More likely to work for the allies than London Calling will work for the Axis.
#3-Poor Morale-Since the Italian divisions are frequently eliminated due to not having battlegroups anyway, this card really doesn't hurt the axis much. However, culling the deck may be worth it.
#4-Disengage-Fairly useless, since you still get all of the step losses.
#5-Taranto Raid-Painful to lose such a great card, but 1VP could make a real difference late in the game. I'd play it.
#6-Naval Shore Bombardment-Cull this card the first chance you get.
#8-Mediterranean Fleet-You must hold this card to keep the axis guessing.
#9-Compass-The Italians are unlikely to stay next the Brits due to this card, so you may have to play it just for movement to cull it from the deck.
#10/#33-Ultra-Knowing the axis cards is nice, but I wouldn't hold to wait for the right moment. Just play it early in the turn.
#12-Minefields-This can really save the day to keep Panzers out of bad spots (Mersa Matruh). Save this for the right moment if you can.
#13-Matildas-A very good card. Counter-intuitive, but probably best used in East Africa (Keren).
#17-Long Range Desert Group-Doesn't seem useful to me, but I guess it depends on how well you roll on the raids.
#18-Ethiopian Campaign-East Africa can be conquered without this, but it sure makes it easier.
#19-Auchinleck-Cull it if you can!
#22-Barbarossa-A must play "."
#23-"Where is Gambara?"-Probably won't make a huge difference, but cull it when you can.
#24/#25/#27/#44-Malta Convoys-Must play.
#26-Exporter-Not as necessary as Ethiopian Campaign or Vulcan, but necessary if you want Beirut.
#28-Atlantic Charter-Must play.
#36-Montgomery-If I'm the axis, you should skip playing this card :>
#40-"Victory or Death"-Possibly a late-game decisive VP.
#48-Malta Victorious-Must play, if you can arrange it.
#51-Vulcan-Must play, IMHO, esp. if Torch comes out late.
#55-Von Arnim Takes Command-If you are sitting on Tripoli, a Rommel column shift is not likely to be a major concern. I'd use the OPS to finish the axis off.
