6 Cost Summoning

The goal of this deck is to use  lockjaw and jubilee to summon 6 costs cards early. 

Lockjaw swaps the next card you play with a card in your hand. Quicksilver will always be in your hand as a cheap card to play to get swapped into a much better card. Jubilee, ON REVEAL, summons a random card from your deck.  The only dissapoinging card to get would be a swapped Quicksilver.

Sunspot is a great card to get at any point in the game. If you get Sunspot in your starting hand, he will gain power from unspent energy until turn 3 (the earliest). If summoned later in the game, Sunspot can still be used as a cheap card that gets a power boost from turns 4-6.

Jessica Jones (ON REVEAL) is in this deck since summoned or not, she can have power on par with the other cards if you do not play a card in her location the next turn. You can also skip turn 5 after summoning her in turn 4 in order to play The Infinaut on turn 6. 

The rest of the deck is comprised of powerful 6 cost cards that have the ability to sway the game in your favor with lucky summons from Lockjaw and Jubilee. For example, say you play Jubilee on turn 4 in an empty location, and her ON REVEAL ability summons Arnim Zola. Arnim Zola's ON REVEAL ability would destroy Jubilee, but copy her to other locations so 2 more cards will be summoned ON REVEAL.

The enphasis on ON REVEAL abilities is because nullifying these abilities is the main counter of this deck. Leech and Cosmo come to mind, since Leech removes the abilities of the cards in your hand, and Cosmo's ONGOING ability nullifies ON REVEAL abilities at his location.
