HAHAHA Beat Hardened Obelisk

So I was on dueling network and someone was playing Unstoppable obelisk, He was at 5000 life points and had obelisk with hardened armed dragons eff on it. And i just drew rank-up magic the seventh one with supply's eff, and I thought that was my only out so I got discouraged. But then I remembered I had 1 last way out but I had to be lucky. (I was playing H.A.Trix btw) I xyz for number 82 and attack direct. Then he destroyed it. So i put it back in the deck with pot of dichotomy, then stalled. I brought back out 82 and attacked directly. He said,"Are you actually trying to beat unstoppable obelisk? Then I made another rank 4 on my turn and he said "Cowboy" And I was like no dawg Digusto emeral, returning 2 traptrix dionea, and 82 back, all i needed to do was draw dionea, and i drew it off of emeral XD. So next turn i brought out 82 and attacked for game XD.

Moral of the story, if you have room and need a rank 4, 82 can be a cowboy in some situations!

question

u used pot of ditchtomy and u said you brought back 82

even if you summon it , you cant attack cause of the ditch and obelisk would kill and you cant bring it back
if you dont summon it, obelisk would direct for win
how did you do it?

Easy I stalled out for next turn when I could attack
I attack directly 3 times when he had 5000

how did ya?

I think just special summoning artifacts in def
