If you can add
Wydwen, the Biting Gale into your actual deck list, just put the comment "Commander" above her to make it clear. I had to look up what the card was on gatherer.
I'm personally not sure about the equipment package, as they are all sorcery speed. The fact that you need to speed
5 to cast and equip is a recipe to get blown out on your normally reactive plan.
Cryptic Command is great as you can use the "Return target permanent to its owner's hand." to get additional value out of your ETB creatures.
Shark Typhoon is basically another flash creature.
Cloudstone Curio and
Equilibrium are options for additional ETB effects AND saving your creatures from targeted removal.
I also like
Commit // Memory,
Wretched Confluence,
Pull from Tomorrow,
Archmage's Charm,
Chain of Vapor in this deck as they are very versatile cards for the whole reactive plan.
Commit can be used on the stack and permanents, and then the
Memory part can be timed after you've cast
Notion Thief.
Wretched Confluence can be simply draw 3 cards, but its other modes can be used to destroy creatures or get back some great ultity creatures from graveyard.
Pull from Tomorrow just for a way to scale up card draw with mana available.
If you can afford it then
Sapphire Medallion is just another card like
Naiad of Hidden Coves and
Cunning Nightbonder as almost 80% of your deck is blue.
