Perfect! It limits Extra Deck without requiring deck tinkering for Link Monsters; This could become an actual alternative format I might use with friends IRL and suggest to a few of my online pals, too. 

As far as Life Points are concerned; 8000 is probably the safe bet. 4k is still pretty low; It's not difficult to do 4k in one turn still, depending on the hand.

My character, her Guardian Monster, as well as her Ancient Gear and Roid decks, are complete; I'm currently making concepts for my custom cards.
