We have to wait, for now take vortex as a reddit card: an overhyped card based in what it did in tcg that ends up seeing no play in duel links.
If the card turns out to be game changing then you'll still have your gems as opposite of what would happen if you spend now and then it ends up being a dud
Personal opinion: I tried running at 3 for a while and it only got me otk, I drew it first hand then I got otk tons of times next turn, I'd rather draw into karma or floodgate first turn.
Then I run less copies and it never appeared when I needed it the most or came too late when I had nothing to discard
^ and when I say nothing to discard I mean the other card was a really important one
I had to decide: use it to rebuild the field or discard it to wipe opp field and pray then don't top deck a comeback.......thing that always happened
The chance of bricking is exactly why most players wouldn't want to run this card. Even blue eyes would rather draw karma cut to avoid turn 1 brick.
As for someone who doesn't own 1 but faced opponents that do, if they can't win that same turn it's all for nothing, I will simply summon new monsters on my next turn. Hardly relevant right now, maybe in the future, depending on meta decks.
