@Rainbolt Sure. If you never exercise the option, then it's like you never had it. And you do, then it's just as bad. But purposely choosing to leave that option open implies that you intend to exercise it at some point.
Sure. Probably the easiest example is if my opponent pulls the exact same thing on me, and then calls me on it. At that point, I adjust my definition of sporstmanlike to include anything that is legal.
Okay, I provided one specific situation where I would play like that. You then concluded that it was the only situation where I would play like that. "You would [...] unless [...]."
So just to be clear, there are numerous situations where I would play like that
And in fact that is how I have been playing for some time now, and have never had an issue with it
It's not exactly something you can do anything about unless you counter the Gigadrowse copies, which just puts you down a card anyway.
Real example (this actually happened to me): Opponent has a Treetop Village and Scavenging Ooze. I am at 2 life with Cryptic Command in hand. He offers to move to the beginning of combat. I say okay. He swings with his Scavenging Ooze. I say "Whoah, hang on a second. We are in the beginning of combat." He calls a judge and the judge agrees. I can tell that his actions were calculated, and so for the rest of that game I am playing competitively (or as you call it, "unsportsmanlike").
I think this simply boils down to a difference of opinion. "Sportsmanlike" is subjective. In my opinion, there are many tiers of play, and you can't simply point to something and say "This is unsportsmanlike." without also specifying at what tiers you consider it so. You may not even play Magic at a level where such an action is ever sportsmanlike.
Beginner: Offer free and derived information without being prompted. Protect your opponent from stupid mistakes. Intermediate: Only offer free and derived information when prompted. Offer information that requires intricate rules knowledge witho…
So when you say "That action is unsportsmanlike [at all levels of play].", I hear "That action is unsportsmanlike [at all levels that I have played]."
I basically disagree with your first paragraph. In the general sense, being a jerk doesn't suddenly become OK at a higher REL. And in this particular case, the way I see it is that Magic is a competition of deck building, strategy, and rules knowledge, not memorizing exact card wordings, and that doesn't change in different levels.
And I think there's a real difference between not explicitly providing some information, and deliberately (but implicitly) providing subtly wrong information
From another L2 Judge: "You can't know what your opponent knows or doesn't know about the cards you're playing with. If your opponent isn't clear on what your cards do, it's his responsibility to ask you, or even better, a judge."
Oracle text is considered derived information at Competitive and Professional REL. It's free information at Regular according to this L3 Judge. That pretty much debunks your theory about how, as you put it, "being a jerk doesn't suddenly become okay at higher RELs".
I know that you are allowed to use the card. But this is a particular case of "deliberately using the pre-errata text of a card that has received functional errata for the purpose of misleading an opponent about free or derived information" It just seems like an abuse of a corner case to gain an advantage that is allowed only because it would be overly burdensome to outlaw it.
@murgatroid99 Keep in mind that you are the one taking the extreme viewpoint here. I could get on board with "It is unsportsmanlike at some levels of play." But all levels of play? That's just ridiculous.
@JonTheMon Just to be clear, are we asking if it is legal, or are we asking if it is sportsmanlike?
If I ask how many cards you have in your hand, I have added to your burden. You must answer me and tell the truth. It's neither legal nor unsportsmanlike for me to do that.
On the other hand, if I use old card texts as we have been discussing, then I have added to your burden, but I would consider is sportsmanlike only at the highest levels of competitive play.
Here's another perspective. A while back we were playing a 2HG game against some friends. My roommate misunderstood a card and wanted to take back a play. Opponents offered "Do you want to play for real or for fun? If you want to play for fun then I don't mind letting you take it back." My roommate said "No, nevermind. We'll play on." Now why do you think he did that?
That's pretty much what I think (assuming higher REL yields higher competition, which most of the time it does). I think my roommate gets more enjoyment out of winning when the opponent is not giving out freebies.
Yea, the philosophy doesn't line up. They say that they are fine with the NAP being extra proactive during the draw step, but it's not okay for the AP to be extra proactive during the beginning of combat.
I'm not super worried about it because I don't have anything to do in my beginning of combat with my modern deck, and that's the only format I really care about.
I actually enjoy the protection of this rule, since I play Cryptic Command which is a highly interactive card at these stages of the game.
@Rainbolt The one time I have wanted to do this, I needed to let mana leave my opponent's mana pool in their main phase so that I could activate manlands without my opponent being able to cast a removal spell.
