Vulture is one of my staples with earth splinter. I bought a level 4 gold foil and never look back. Think is the best opportunity monster for 3 mana.

I have not used Nectar Queen but feel it can be a very good tank card. Put in Wood Nymph to heal this. Definitely agree in earthquake rule set Vulture and Nectar are useful.

Cube is by far one of my favorites. When ever I see LoA in opponent's previous match I plan around the Cube. I have fared well neutralizing LoA with the Cube. Again going gold foil cube for bigger jump in leveling and less time to accumulate the cards to hit level 4/5.
