First of all, hello to all.

I want to make a denial deck, but I need some help with it and would appreciate it very much, if the more experienced could help me. I plan to use darkness, earth and gravity together, but I cannot decide about some things. Please note that I have no upgraded cards (except a quantum tower and a supernova), and only a few weapons.
Here is the base of the deck.
55k 55k 55k 55k 55k 55k 55v 55v 55v 55v 55v 55v 58o 58o 58o 58o 58o 58o 593 593 593 593 593 593 5um 5um 5um 5um 5um 5um 5up 5up
So:
-I need some way to deal damage. Draining their quanta is good, but it won't hurt them physically. Any ideas what creatures should I use?
-I don't know if the number of pillars is appropriate. Do I need more, or maybe less?
-Weapon and shield?
Thank you in advance!
