If you want to make an upped PvP deck, a few good options are:
Fractal Charger
Fractal Phoenix
Aether with Protect Artifacts
Shrieker Rush
Rainbow Rush
Mono Entropy antimatter
Gravity control deck
Golem Rush
Fire Stall
Those are some of the more commonly used decks. My favorite is probably the rainbow rush, because it can be the most versatile. However, if you want to play a mono entropy deck, A good place to start would be here:
6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6ts 6tv 6tv 6tv 6tv 6tv 6tv 6u5 6u7 6u7 6u7 6u7 6u7 6u7 6ug
I have the nymph, but if you don't, just take it out and add another pillar and the deck will work the same essentially. Basic strategy is to antimatter any strong creatures your opponent puts out and then when you have enough quanta to play an antimatter and a dragon, play a dragon.
You can also replace the discord / nymph with two UNUPPED dissipation shields if you don't have those rares.
