Grow the rulestring! (Game)

Heya friendly folk! I've decided to propose this fun little game of mine, which I'd call "Grow the rulestring!". Although I'm currently thinking of a better name than that heh. Additionally, I've had a feeling this kind of game has been made before on these forums, however I haven't encountered it yet (if that's the case, perhaps this could be a fresh start?) The rules are quite simple, and easy to follow.
Rules:
- The game starts with a simple, dead rule. B/S. That's it for now.
- Your goal is to extend this rule, by adding more rules to it, an example would be: B/S becoming B2/S, by addition of the new B2.
- INT rules are allowed as well, and I've decided that you can add both the corresponding letter and the rule (e.g B/S becomes B2a/S) This rule also complicates things a bit, as there is also a (-) included in some of the rulestrings. For the sake of the game however, lets try our best not to use it ehehe...
- You can only add one rule per post, no more than that.
- You cannot remove rules, once a new rule is set in, it's there permanently, so no reducing rules to nothing!
Also, please cooperate folks. I believe we can make a rule together as a community! I'm excited to see the kinds of interesting patterns we produce from these
With all that being said, let's start with this rule! Have fun my friends!
also, as a fun reminder, I'll update the current rule as soon as possible! The current rule is:
Code: Select all
x = 1, y = 1, rule = B2ac3nq4i5er/S1c2n3a

The rule now goes explosive(and will keep so for some time)
Interesting things still happen though:
Code: Select all
x = 4, y = 6, rule = B2a/S

Do you know what's better than a rule with replicators everywhere? A rule with replicators
and puffers everywhere!
Code:
Select all
x = 10, y = 8, rule = B2ac/S1c3a

Goodbye, chaos. Rest in peace.

This thread is similar to
Pass the Rule but no removing conditions/transitions/consitions/tranditions.
EDIT: this thread is suspiciously similar to
Counting to 50 with transitions, especially since both don't allow deletion.
EDIT 2:
Adding B5e to enable more line puffers:
Code: Select all
x = 5, y = 8, rule = B2ac3n4i5er/S1c2n3a

Added 4r to brith notation. Not exactly sure what that affected, but we still got a lot of rakes and puffers.
