- It gives you more strategic possibilities to use the spell, like making sure it does not stop at a wall that blocks LoS.
It could easily be worded around this. lots of effects (pushes, and teleports, etc) don't need LOS, and at most it needs a "this subsequent attack doesn't need LOS from the previous zone" in the text.
It would not be weird if you would describe the card:
"When Tsunami is cast, the mage chooses a direction. After Tsunami is done attacking the zone it was cast to, the mage may cast Tsunami again to the next zone at no additional mana cost, following the chosen direction while ignoring the spell distance. Tsunami stops repeating when it reaches an Arena wall. When a situation arises that would not allow the mage to re-cast Tsunami - for example when he has no longer LoS to the zone where the next attack would need to take place - the Tsunami attack stops repeating as well."
Honestly that sounds nothing like a Tsunami to me. Call it a linear maelstrom, or chain explosion, or something, but it's not a Tsunami...
"The initial target of Tsunami is considered the source of all further damage and effects of this spell"
Something like that could work. I'm not sure if it would be as clear to everyone as it is in your head though. Often times things that we think are super straightforward turn out to be a lot more confusing and complicated than we at first give them credit for.
Agreed - it was a genuine open question asking why that approach couldn't work, and whether it broke something else in turn. It's always easy enough to point out the flaws in someone else's idea/wording and I do it all the time, it may be that fresh eyes find something equally problematic with mine - I can't currently see a downside (other than it's errata on a card that's already gone to print).
Such as saying a spell uses the standard rules that everyone has been playing by for years, just as an example.
Agreed. Whilst it is true that it's using the standard rules we've always used, it's also using then in a combination that gives results that few would naturally grok at first pass.
Something else to consider when describing the effect you want, is that space on a card is at a premium. I'm not certain how much this played into Tsunami's design, and I think it could perhaps fit another short sentence on it, but you can only fit so much on a tiny piece of cardboard and that does always need to be considered.
Actually, I had originally written a short para on that, and deleted it as off topic. To be honest, given that the card is printed, the full text is likely to only exist in the rules supplement, not on the card, so that's less of an issue. That said, I'm sure you could word this such that it would fit on the card, and if push comes to shove, I'd rather have a reduced font to accommodate (already done on a lot of cards).
You've expressed how you'd like it to work and given what may be a feasible solution. Will just have to wait and see if Arcane Wonders decides to make such a change.
Honestly, I doubt they will. Although they often tinker with adding a subtype, they very rarely issue big errata like this - it's essentially happened once in 2013 at the game's start, and just recently with Wizard/Tower (which should have happened a couple of years earlier).
I'd like to see this work differently, because how it actually works is a mess and unintuitive. AW has only applied non-subtype errata for power level, not just because something could have been designed better. The card won't be broken as printed, and not unplayable either, so it doesn't have a power level problem.
