A simple build of purrely for Cyberstorm access. The deck aims to make Noir on turn 1, and break board by abusing non OPT clauses on purrely cards, back by Adventure engine. The adventure package offers removal in the main deck with illegal knight and dracosack, and negates from griffin to insulate plays. You do give up the normal summon effects, but it is easy to play around since you don't alot of cards during the main phase.
There are 2 lines that I think is fun. Eppurely Happiness is not once per turn. You can swing with happiness, search happy memory and activate it to prevent a monster your opponnent controls from in battle. At the same time, happiness' non-targetting attack reduction let you chip away at the life point. This lets you attack with Happiness 4 times in 1 turn. This comes with the upside of having 5 material for Noir.
The second fun line is with PurrelyYeap?! Stacking multiple Sleeping Memory enables multiple draws during SP. PurrelyYeap lets you double those draws. You can draw up to 6 cards during SP! You can also flip this on a Happiness and repeat the previouse line with Expurrely Happiness.
The spells are not that great.They are great consistency booster, like Runicks. However, unlike Runick cards, the spells only offer protection(and Sleeping Memory does nothing) if you cannot access the extra deck. The monsters you summon are weenies, and you can't use BP to bait out interactions on cards like IP.
At the end of the day, the non-OPT clause on most Purrely cards makes for a really fun time.
