Before tokens were introduced i played defensive Alliance deck with overcosted attack cards like orc regiment. x6 productions with the shrine of miriam or x20 recruits with the dark forge were awesome.
Tower-attack decks are very conditional, so they were not very interesting to me.
Pure barbarians, soldiers, undeads and beasts were not very effective in my hands, so i dont play them.
Among pure decks unliving, brigands and mages were preferable, but still not very powerful. I decided that pure-keyword decks are weak.
So i began arranging shuffled decks.
The first one was not-unliving tower-builder deck. An idea of accumulating bricks for numerous builder-cards with swift-gem-costers and stealing-brigands-recruit-costers was quite playable with win ratio about 70%.
The second idea was to put overpowered cards from different decks together, namely: legends, frenzy, vampire, divine intervention, sorcerer's outpost, death wave and such.
I was very skeptical about this experiment, but it was stunningly successful. I played this deck a bit and became bored.
The third one was quite interesting brigand/undead deck. Very good deck, but very boring. I decided to return to overpowered-cards-mix deck.
After last update i refined that deck to make fast-destruction one: removed legends, added new quick common hand-refreshers and placed it on holy keyword basis for fast resource accumulation. It is the deck i play now. It is so effective that i already had three failed attempts to create more powerful deck and made under-15-turn-wins of games against virtually everyone.
Thus, i will wait for "nullify"-keyword introduction to make something new.
