I'm trying to build a Fate/ Sorc subclass and would like feedback and suggestions on how to emulate the aspects of heroic spirts that we've seen in the numerous media. 

Combat Magic

At 1st level, You learn additional spells when you reach certain levels in this class, as shown on the Combat Spells table. Each spell counts as a sorcerer spell for you, but it doesn’t count against the number of sorcerer spells you know.

Whenever you gain a sorcerer level, you can replace one spell you gained from this feature with another spell of the same level. The new spell must be a conjuration or a evocation spell from the sorcerer, paladin, or ranger spell list.

Weapon Summon 

You freely conjure a weapon in your empty hand, which you are proficient with while wielding.  They count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage. You choose the form the weapon takes each time you create it and you can't be disarmed of that weapon unless you are incapacitated. You can have up to two conjured weapons and can summon both at the same time with a bonus action. If they are on the same plane of existence, you can summon them, causing it to teleport instantly to your hands.

Extra Attack

Starting at 6th level, you can attack twice, instead of once, whenever you take the Attack action on your turn. 

Arcane Strike

At 14th level, After you take the Attack action, you can cast a Sorcerer spell as a bonus action.

Unlimited Bladeworks

this is where I need help, I was thinking a reality marble type feature, but im not sure how to implement it.
