You can keep a lot with this deck but finding crystology is pretty important. Know your gameplan. Vs aggro you dont have to keep the lens but vs anything else its pretty important to have that wincondition.
This deck is super fun and actually quite good. Still working on it but you get the idea: Get all your 1-Attack minions out of your deck for midgame and then swap decks with a Lensed togwaggle or azalina. With this deck you dont even have to wait until you have drawn your whole deck to swap because the deck without the combo or quest is incredibly bad by itself.
Also dont panic when you draw togwaggle or azalina before the lens. This deck can also win with the sheer value of spikeridge steeds and the quest.
Good luck with this and have fun!
