The hardest special mission is probably Consecrated Ground or Phase Crystal. I haven't played either of these, but I know that Consecrated Ground has only Apprentices and Super Monkeys (which many people don't have many of) and the Phase Crystal is a really hard track with bloons that are twice the speed (with a tech terror crystal in the middle, which I saw in a video doesn't really help against the early rounds. The scary part about the mission is probably the pink bloons... but what if a DDT came? O.O). Both are required for really high level 4th tier upgrades (ToMG and Ray of Doom).

The next hardest one is probably MOAB Graveyard, but with x|3 Spactories and enough popping power in the back (should include a 3|x Ice Monkey) to pop the ceramics (you should also get MOAB Maulers against the ZOMGs) makes your reward of 5000 Bloontonium, 1000 City Cash and bunches of XP yours easily.

Next is Shipwreck is because all land towers are double price, the bloons are upgraded, and the only perks you get are the 5 whirlpools, which honestly don't help much in the later rounds, albeit good bloon popping power.

The next hardest is the Tranquil Glade. I chose this instead of the Sticky Sap Plant because of the fact that the only good thing you get from the mission is $500 extra starting cash. In Sticky Sap Plant, you get two amazing plants that can glue all bloons on the screen (also, the bloons aren't all camo and there aren't any tower restrictions).

Next is Stick Sap Plant. The reason this isn't that hard is that if you aren't afraid to use the Sticky Sap Plant ability (it recharges fast and you have 2 of them), then you can get enough money (since there is more bloons, there is more money) to buy the upgrades you need to beat the bloons (and the few MOABs that come on the last level).

Last is the Wattle Trees, as if you spam 3|2 or 2|3 boomerangs (which you basically have to do), you can win the mission automagically. Getting free boomerangs every three rounds is pretty awesome, and I have yet to see a MOAB come during this mission. And the special item is pretty cool too.
