3. Should this section include something about sideboards? Right now the word "sideboard" only appears in the glossary.
4. I like the zones picture a lot, but I think it would help if it included momentum and the RFG pile.
4.0.2 and 4.0.3 I like these. They're simple and clear. It's weird to not be in any kind of zone, but 4.0.3 deals with the weirdness nicely. It's a bit funny that attached cards are more removed from the game than RFG cards. (:
4.0.4 This is good. Shouldn't there also be an explicit rule that if cards are moved from one hidden area to another hidden area, then they are _not_ revealed?
4.2.5 This could possibly use a note that cards added to the momentum face-up (by card effects) are the exception.
4.6 "While a player’s hand is not on the playing surface, it is considered an area of play and can be affected by cards and abilities." The first time I read this, I thought "while" was a timing word. I suggest changing "While" to "Though" for clarity.
4.6.2 is followed by an extra carriage return.
4.7.4.1 "When a player is required to cycle their deck, the entire game including any effects is paused until the player is finished cycling his deck." The phrase "cycle their deck," should be "cycle his deck," to match "cycling his deck" at the end of the sentence.
6.5 "Any reference to the active player, specifically references the player whose turn it is." The comma here is a comma splice, and should be removed.
7.6 The timing here is unclear. When is "now" ? Perhaps this should be, "After a player has drawn cards during the draw step, the player moves on to the next phase of their turn." Also, note that "onto" should be "on to" (two words), since the "on" is part of the phrase "moves on".
Unfortunately, this still leaves a lot of timing really unclear, and I'm not sure what to do about it. I'm refering to Response abilities and their effects. For instance, if a Response triggers, "After your opponent draws one or more cards," and you activate the ability when your opponent draws cards in the Draw Step, is your Response taking place in the Combat Phase? Or does the Draw Step wait around until all responses (or triggered continuous abilities) finish resolving?
The same problem occurs with Responses played "after" any action that would normally end a step or phase.
