Strategy for building up deck

Hello,all i will try to share the things i learned in building up your deck.
Firstly i buy VENARI WAVESMITH for the water deck and go about 80% winrate with the water deck with it;
and grind to 800 raiting.
After that i rent in some Gold fire cards:
Pyre,SERPENTINE SPY,FIRE BEETLE,MOLTEN OGRE,FLAME MONKEY,GOBLIN SHAMAN,ANT MINERS.
Which gives you a nice boost to dec earning,those cards are worth arround 100/dec a day,
you can get arround 10 dek a win with them,making 200 dec a day slowly building a deck.
Once you get 1000 raiting you can do 4 points in your daily quest(while in bronze),and then rent in enought power for the quest you need that will get you to silver,netting you 2 chests from the daily quest,which are
better quality from those in bronze.
