A short review of Ayakashi Ghost Guild!
This game is best in series or one of the top 2! One of the first things I have to say is using an invite code when you join is nessesary! It's almost dumb not to. I used "cardbonus" from the official android market reviews page. You get rewards for doing so over 7 days. Most of these awards you recieve are only attainable through using "Real Money" or getting lucky via storyline ;).
The game's goal is to create strong atk decks and strong def decks and collect as many rare cards as possable. What you would do with these cards later on is unknown besides having bragging rights to friends of yours who also play the game. Cards are obtained by summoning or going through storyline or special events.
You have to build your decks certain ways because every card has an "Spirit Requirement" and if you only have 20 atk spirit and 20 def spirit and have a 20 spirit req. card you will only be able to keep that one card in your deck. I think maximum is 5. Use lesser cards that are leveled up for awhile before going for higher cards. Worry more about increasing your health to a decent lvl.
Now the game starts off kindof slow..And makes you want to check your phone every 20 minutes to use up your 20 or so health points. Just a tip I can give is get your health to about 60-90 and that will give you 1hour to 1 1/2 hours before your health regenerates totally.
Zynga holds special events for this game and one of them runnign right now is Halloween Tower. In the tower you have to try to reach certain levels to attain guardian ghosts! And you also collect halloween cookies and trade for cards on your way up. Take full advantage of these special events for there more rewarding than the storyling.
All I have for tips. Hope you guys enjoy playing Ayakashi Ghost Guild!
