Slifer The Sky Dragon vs. Obelisk The Tormentor | Yu-Gi-Oh Master Duel 

Loading screen checks out

Obelisk for the win

there's supposed to be a special punch animation when you finish the opponent with Obelisk??

What was that spell card you used to tribute summon obolisk?

Since you had the metal reflect slime trap you could put God Slime in the extra deck since it only needs Guardian Slime or Reflect Slime to summon, then with God Slime's effect you could use it as 3 tributes. I play a god deck :p

since whene are there summon animations like THAT?

Is there a link where we can play this game?
