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.
