Drop and walk, the line-up

Sometimes we just want to drop something into a recently captured gym and walk on. I'm primarily thinking of the three first open spots in a gym.

If it's a gym you couldn't care less about it's probably a bad idea dropping your best defender inside. Still, if you drop anything at all you should still give it a thought.

• Bragging rights, exceptionally rare pokemon
• Bragging rights, an IV 100 maxed out 'fun' pokemon
• PITA, it's going to hurt attacking this gym
• PITA, it's going to take time attacking this gym
• Builder, prestige pokemon

Let's focus on PITA and Builder

It's going to hurt, Minimum CP, Name, Attacks:

• CP 2800, Dragonite, Dragon Tail / Outrage
• CP 2900, Tyranitar, Iron Tail / Crunch
• CP 2700, Gyarados, Dragon Tail / Outrage
• CP 2700, Vaporeon Water Gun / Aqua Tail
• CP 2800, Rhydon  Mud Slap / Stone Edge
• CP 2500, Snorlax, Zen Headbutt / Body Slam
• CP 2400, Blissey, Zen Headbutt / Dazzling Gleam
• CP 2400, Exeggutor, Confusion / Seed Bomb

It's going to take time:

• CP 1000, Chansey
• CP 2400, Blissey
• CP 2700, Snorlax

Builder:

• CP 2600 or lower Gyarados with Bite / Twister
• CP 2700 or lower Dragonite with Steel Wing / Hyper Beam
• CP 2600 or lower Rhydon with Rock Smash / Megahorn
• CP 2800 or lower Tyranitar with Bite / Fireblast
• CP 2600 or lower Flareon with Ember / Heatwave
• CP 40 Gastly with Astonish (or any other dedicated Bubble Strat defender)

When you feel fairly confident the gym's going down soon just aim at PITA. If you believe your team mates might arrive and build the gym drop a Builder.

The reason for the low CP of the builders is that you really don't plan to be left inside the gym. You deliberately place a crap defender inside with low enough CP that it'll occupy the bottom most place until it's booted out of the gym.

With the exception of chansey and vaporeon you should be able to catch the pokemon listed above in the wild. You probably already have some of them, which was taken into account for making this list.

The chansey is listed in case you already did build a bouncer with the express purpose of defending just about everything else, and the vaporeon is there to show that you can use them ocasioally while you're actively powering one up.
