Hearthstone Filter by Keywords

I have already experimented successfully for the following filter keywords in case you want to construct a classic deck + previous/current year expansion/adventure.

1. Basic
2. Classic
3. Nax
4. GvG
5. TGT
6. LoE
7. Lengendary

Case is not sensitive i.e. it does not matter it is upper or lower case.

Now, everyone, get in here! (oops, it's nerfed...)
