User blog:Milesprower2/My Pyramid of Doom guide

Here's a guide I've made to help beat the Pyramid of Doom in PvZ2. I'll post guides to the other Challenge Zones when I play them enough to develop good strategies for them. If you have any questions or comments, post them in the comments section, obviously.

This is a guide to the later levels, like 10+ and even as high as 30+, not the early levels. You can adapt this strategy for use in the early levels if you want to however.

Also, it works best if you've unlocked all plants you can for Pyramid of Doom, so you will always get a choice of bonus starting Sun.

The plants
So, here is a list of the plants you'll need:
 * Twin Sunflower (highly recommended for 25+).
 * Bloomerang.
 * Wall-nut.
 * Winter Melon.
 * Grave Buster (only if there are lots of graves).
 * Chili Bean/Potato Mine (Chili is better in general, but Potato Mine should be used instead if you're fighting Pharaohs).
 * Iceberg Lettuce (for stalling tactics and early Explorers)

The zombies
A list of the more dangerous zombies, and some good ways to fend them off while you are still building up your defenses.

Buckethead Mummy
This can actually be the third zombie that shows up, and they will appear in large numbers before even the first flag. Chili Beans, Winter Melons, or two Bloomerangs with a Wall-nut are the best ways to deal with them.

Tomb Raiser Zombie
This guy is a pain when he summons more graves, but there isn't much you can do about him until you have three Bloomerangs or a Winter Melon, as Iceberg Lettuces are better saved for tougher zombies.

Explorer Zombie
This guy will wreck your defenses easily if you give him the chance. Use an Iceberg Lettuce if there are defenses in that row, or two Bloomerangs can also suffice. One Winter Melon does the trick too. Don't use Chili Beans, they're useless while the torch is lit, and Potato Mines are probably useless too (I dunno for certain though). If the worst comes to the worst, use a Power-up to deal with him, and all the other zombies that are around while you're at it.

Pharaoh Zombie
The biggest threat, this guy is immune to Chili Beans while the Sarcophagus is intact, and other instant-kills simply destroy the Sarcophagus. A Winter Melon and Wall-nut with a Bloomerang or three Bloomerangs and a Wall-nut are the only good ways to deal with him early on, unless you want to use a Power-up to make it easier.

The actual strategy
Start off with a Twin Sunflower as soon as you can afford it, and use one Plant Food on it. Continue to build your economy, bust graves and kill off the early zombies with instants. One column of Twin Sunflowers will be enough. Hold off the early zombies WITHOUT spending any more Plant Food, unless you're maxed out and a zombie drops additional Plant Food, then spend it on your economy (Note: If a zombie is getting through your defenses and you get spare Plant Food, don't be afraid to use it to kill the zombie instead). Get two Winter Melons by the first flag in any level (they should be placed in the second and fourth rows, in the second column), along with three to five Wall-nuts.

For one flag levels, fill the third and fourth columns with Bloomerangs, and the fifth with Wall-nuts.

For two flag levels, do the same but fill in the empty space in the second column with more Winter Melons.

For three and four flag levels, go for three columns of Bloomerangs, not two.

This strategy can survive using only one Plant Food per level up to level 28 (and probably beyond, that's just the level I've reached so far, and I'm still alive with all Lawnmowers), but some levels may require a second use of Plant Food (on economy or offense, not defense), especially if there are Pharaohs.
