I reckon Consecrated Grounds might be difficult. Sticky Sap isn't too bad, if you have the right towers. MOAB Graveyards are the same every time, so it won't be that hard. Phase Crystals used to be difficult, but it might not be anymore (will attempt later).

Currently in my city, I see:
 * 3 MOAB Graveyards (1 out of range)
 * Phase Crystals (will attempt)
 * 2 Shipwrecks (1 out of range)
 * 2 Sticky Saps (1 completed, 1 out of range)
 * 1 Tranquil Glade (out of range)
 * 2 Wattle Trees (1 completed, 1 out of range)
