It is really cheap and the reason I use that wired amount of rare cards is that is all in my collections.
If you have more, add them to your deck, but always take care to leave more positions to quick spells because AI will not expect that.
How to win:
Try to keep 1 cost card unit in your hand for the beginning.
Try to attack every turn and use our tons of fast spells (
Torch,
Finest Hour,
Rampage,
Shugo Standard) to kill AI's unit or use
Elder's Feather to dodge their block.
Use
Sword of Icaria,
Retribution to kill high threaten units of AI.
For replacements:
Censari Brigand is really good with those overwhelm spells but I think it is also fine if you don't have them.
Nimble Conscript can also do good jobs.
Unseen Commando is good for attack because we have some double-battle-skilled units and it is also flying unit. If you don't have, use
Silverwing Familiar to replace.
Hope you enjoy my deck and also hope to hear your comments!
