Pokemon Go Guide: How to Catch Rare Pokemon in Pokemon Go

As you play Pokemon Go, you'll be preoccupied with three goals; leveling your Trainer as high as you can, evolving and powering up your creatures to attack and defend Gyms, and filling out your Pokedex with new, rare Pokemon. You'll find that all three are connected, as the higher your trainer level, the higher your chances of finding rare Pokemon become, and in many cases, rarer Pokemon tend to be the best in Pokemon Go.
Bulbasaur, Squirtle, Charmander, Dragonite and even Pikachu are examples of rare Pokemon in Pokemon Go. Players of these game from around the world are desperately searching for these rare Pokemon in their neighborhood. Here are some of the game's tips and tricks on finding and catching these Pokemon.

Pikachu tops the list of most wanted rare Pokemon. This cute tiny mouse Pokemon has been loved by everyone ever since its debut, and players want to add it to their Pokedex. For first timers, you can acquire Pikachu easily as your starting Pokemon. This famous trick has been used by several players nowadays. Simply by moving away from the three starter Pokemon during selection, a wild Pikachu will appear after 2-5 re-spawns.
For those who just recently started the game, you can start from the beginning by clearing all the data on the Application Manager. This will allow you to use the 'Pikachu trick'. According to the reports from The Bitbag, Pikachu could be possibly found near parks or railway tracks. However, there is no guarantee that you will find Pikachu on these cited places. The 'Pikachu trick' is still your best option.

Dragonite is next on the list. Why? Originally reported from Mobile & Apps, the site said that Dragonite is the strongest Pokemon in the game right now, apart from being considered as a Legendary Pokemon in the original series. If you want a stronger Pokemon in your line up, then no doubt Dragonite gets that spot. There are a number of ways on how to catch this Dragon type Pokemon. Maybe by catching it instantly or find a Dratini and evolve it to Dragonite later or even have one by hatching your lucky eggs but it is just sheer luck.
Dragonite can be mostly found on the streets or forest but it is likely a rare catch. You can perhaps increase your chances by installing lure modules near PokeStops. But the best chance for you to acquire a Dragonite is to catch a Dratini because it is an easier catch. Dratini can be found on areas near bodies of water like rivers and lakes. It will require 125 Dratini candies for the Dragonite evolution, 25 for Dragonair and 100 for Dragonite.
Exeggutor is also a challenging Pokemon to defeat for many players. However, Exeggutor has a double weakness to Bug Type Moves. Bug Bite is better than Fury Cutter, but either will be effective against Exeggutor. For Charge Moves, Megahorn, Bug Buzz and X-Scissor are very effective against Exeggutor.
Pinsir and Scyther are both good against Exeggutor. Although underpowered CP wise, Butterfree is also a great counter to Exeggutor because of its Movesets. Venomoth and Parasect are good choices as well, but you just have to be careful when using Venomoth as it is vulnerable to Exeggutor's Psychic Type Moves.
