 ### *Battlement* Cycle
 
-These are a cycle of Legendary Lands for each of the decks with the custom Battlement subtyle. The Gatewatch versions are all mechanically similar, tapping for on-colour mana, providing 2 additional planeswalker loyalty, and having an on-theme ability. Bolas's version is different, representing his "evil lair" and providing a way to quickly summon his generals. The power of these lands is offset significantly by the fact that they are in the deck's 98, not the command zone, so finding them is tricky, and they will swing games when found.

 ## How To Play *Archenemy: Nicol Bolas, Reimagined*
 
-In terms of actual gameplay, there is one major change and one minor change from the original *Archenemy: Nicol Bolas*. The larger change is to provide consistent life totals for the larger decks and slower format; the small change gives Nicol Bolas a special ability when he is close to death:
+In terms of actual gameplay, there are two major rules changes from the original *Archenemy: Nicol Bolas*.
+
+* Life totals follow a variable formula. First choose a starting Gatewatch life total of either 20, 30, or 40 life; each member of the Gatewatch starts with that life total. Then, calculate Bolas's life total as follows: Gatewatch life total plus 10 times the number of Gatewatch members.
+
+   For a few examples:
+
+   * 3-vs-1, 20 starting: Gatewatch 20, Bolas 50 (20 + 10 * 3)
+   * 2-vs-1, 40 starting: Gatewatch 40, Bolas 60 (40 + 10 * 2)
+   * 4-vs-1, 40 starting: Gatewatch 40, Bolas 80 (40 + 10 * 4)
+
+   This should provide a significant life edge for Bolas in a consistent way regardless of the number of players, without being too overwhelming.
+
+* Nicol Bolas gains a special ability to represent a last-ditch effort to stave off defeat:
 
-1. For life totals, first pick a Gatewatch life total; this could be either 20 (same as the original *Archenemy: Nicol Bolas*), 30 or 40. Pick higher values for fewer Gatewatch members or for longer games with more players, or lower values for more Gatewatch members or quicker games. Each Gatewatch member starts with this life total.
-2. Nicol Bolas starts with the same life total as the Gatewatch, plus an additional 10 life for each Gatewatch member. For example, a 3-vs-1 with 40 Gatewatch life means Bolas starts with 70 life (`40 + (10 * 3)`), or a 4-vs-1 with 20 Gatewatch life means Bolas starts with 60 life (`20 + (10 * 4)`). This should give him the life edge he deserves, while preventing the game from going on too long, and avoids the potentially unfair imbalance inherent to a simple doubling of the Gatewatch life for Bolas (i.e. having the same life total in both a 2-vs-1 and a 4-vs-1, the former benefiting Bolas too much and the latter benefiting the Gatewatch too much).
-3. Nicol Bolas has a special ability, useful when he's at less than 10 life, designed to represent his ruthless last-ditch efforts to turn the tide and stave off defeat:
    ```
-   As long as your life total is less than 10, planeswalker spells you cast cost {X} less to cast, where X is 10 minus your life total.
+   As long as your life total is less than 10, planeswalker spells you cast cost {X} less to cast, where X is 10 minus your life total. This affects only generic costs (including Commander taxes).
    ```
-   Thus for example, if Bolas is at 5 life, his Commanders each cost `{5}` less to cast; so ignoring the possible Commander tax, Bolas himself would cost `{U}{G}{R}` and Liliana would cost `{B}{B}` in that situation.
+
+   For example, when at 5 life, with no Commander taxes, the deck's commanders would cost {U}{B}{R} ({5} generic less) and {B}{B} ({4} generic less) to cast.
 
    It probably won't help that much in most games, but we felt it was very flavourful, giving the player one last chance to make an impact with the Commanders before defeat and possibly still being able to cast other spells on that, likely last, turn.
