this rules item seems a bit much of a tempest in a teapot. there are very few places the rules could be an issue. and those are mostly rare circumstances generally. so this is overblown imo. the rules are overwhelmingly solid.
The rules supplement is 46 pages and roughly 27,000 words when thrown into word by the way.
TL;DR If you need 8 examples and 700 words to describe something then the rules are not clear.
It's not about being "solid"; it's about density. The rules are to dense, there are literally thousands of unnecessary words to describe interactions in this game. That's not debatable by the way, it's one of the reason that the game is in the state it is in. Every expansion comes with ~60 cards and a few thousand new words to describe corner case interactions within it. The rules are drafted in such a way to make the game longer and less fun.
Some people don't mind all that and that's fine, but that is not a defense. Look at what I am talking about
"Mage Death
Once a Mage dies, he cannot perform any further actions, pay mana costs, cast spells, make a counterstrike, etc. Any enchantments and equipment attached to himself are immediately destroyed. Other objects he controls in the game remain in play.
If a Mage dies, continue play until the end of that Phase (e.g. the Upkeep Phase, or the current creature's Action Phase.) If all remaining Mages die before the end of that Phase, the game is a draw.
Example: In a two-player game, a Wizard with 1 remaining health and enchanted with Magebane casts an attack spell on the enemy Warlock to kill him. The Warlock is killed and the Wizard will die from the Magebane, and the game will be a draw."
1.) Overcomplicated rules for corner cases are not good and literally bogging down the game.
2.) That example allows for a complete attack sequence to continue when the mage is already "dead". This rule allows for the incredibly rare situation for a draw outcome when there does not need to be. I would argue that this situation is only a detriment to the game as the Warlock, if I were in that position, would be pissed his spell didn't actually kill you and you got to complete an entire attack sequence, even though you were dead and no other creature functions like that in the game, it's only mages for some allow the phase to continue instead of ending the game there.
