These seem much less controversial than last week's ...
1. Wish Boards - I am 100% against wish boards. I have in the past sat down with people who have them. I have agreed to play the game. I was genuinely curious to see how it would go. I've done that three or four times now. It is always the same. The wish board has every potential answer they could need. That wish card effectively becomes any card they could need at the time - a massively modular spell. It's a bit too good. Every time the wish player wins. With normal tutors, you have to dedicate slots in you deck for the tutor targets. This comes at a cost of having fewer slots to dedicate to your deck's goal. Opponents can also interact with that pile of cards ... they can mill your library, force you to discard, etc. A wish board becomes an extra 10 to 15 cards in your library that no one can touch. Too broken. I am now 100% against wish boards. I think it is correct that these effects do not function in EDH.
2. Change the mulligan rule - the original post is a bit vague. I'm guessing that's because
MaRo was a bit vague. Change to what? or change from what? Is this from a time pre-London? Or is he citing a post-London problem? Commander has had a few different mulligan's over the years. Partial Paris was great for the 100 card format, but a bit broken. Vancouver and London are both ok. On the old mtgcommander.net site, they used to give the suggestion that you just chuck your hand and draw a new 7 off the top. No shuffling in between. That is now gone from the new site. I would like to see this policy officially adopted for Commander. It just takes too long to watch 3 players shuffle their 100 card decks for a mulligan, then do it again. Draw 7, toss & draw 7, toss & draw 7, keep, shuffle & London to bottom take much much less time.
3. Life total change - I see no reason to make a change in life total at this point in the format. I've not heard anyone say that 40 life points is too high nor too low. And it is almost one of the defining traits of the format.
4. Planeswalkers as commanders - Didn't we already talk about this last week. Sure that was "any legendary permanent", but planeswalkers are legendary (now). While it would be very flavorful, I am still against it. Planeswalkers are powerful, even the weak ones. They are mostly only balanced by the fact that once they are dealt with (killed), there aren't a lot of ways to recur them from the graveyard. Having access to the most supercharged planeswalker that can come back for the low low price of 2 extra mana is just too much.
5. Change the partner tax - When partner commander first debuted, this is how I initially thought they would function. I would be good with this change. The reality is that WotC could make this change. They invented the partner mechanic and the associated rules. The Commander Rules Committee had nothing to do with it.
6. Commanders hitting the graveyard when they die - This at first seems like a simple change, but if you dig into all the rules ramifications it could be very complicated. If it goes to graveyard, then triggers another movement to command zone, I could
Stifle that trigger and force your Commander to stay in the graveyard. Similar thing with exiling, and even more heinous as I could lock your commander in
exile. If it goes to grave, and then moves to command zone as a state-based effect, then you don't have the option to keep your commander in the graveyard. I think this issue is conceptually tied to the tuck rule. If you always want commanders to always be accessible, then the current rule needs to stand. If you want the tuck rule to come back, then this rule could potentially change too.
MaRo's problem of not being able to design legendary creatures with death triggers is simple. Stop designing EVERY legendary creature specifically for Commander. We have playable commander's that have them - Kokusho,
Child of Alara. Part of Commander's charm is that were taking cards out of the context of their original designs and finding other creative ways to use them.
7. Silver borders - I am for this. I think we need 2 lists. The first is a list of silver border cards that are completely supported by the black border rules.
Crow Storm is a great example here. Nothing about this card couldn't be printed in black border. These cards would be legal all the time. The second list would be a list of cards that, while not completely supported by black border rules, they don't completely break the black border rules. This would be things like "artist matters" cards. These cards would be legal, but you would have to announce at the beginning of the game that you are running them. The final list would be everything else in silver border that wouldn't be banned. These cards would only be legal when specifically playing Un-Commander. I was working on such list a while back. I never completed them.
Now I'm going to go listen to
MaRo's podcast and see if he changes my mind on anything.
