The most important thing moving forward wont be playing the best or most broken deck, but instead finding the one that plays to your strengths and learning the ins and outs of its match-ups
The strategy of this deck is to play your Evasive characters on curve as often as possible , then use your control tools like Dragon Fire, Mother Knows Best, Stampede, and Jasper, Common Crook to control the board and give your Evasive characters an open lane to quest
It's not put into the graveyard
Save a You Came Back (or two) until Ariel is in play, and watch your opponent panic when you go from 5 to 20 lore in a single turn.
I would also put ink acceleration that does not cost you cards from your hand like Mickey Mouse - Detective in this category
As for the card portfolio, this holds up to 80 cards, so it won't let you collect and store an entire set of Winterspell cards, but you can keep your big hits safe and ready to show off to friends
