On the Subject of Points of Order

We are playing weird 4-card KTANE Mao. Play begins with me and proceeds in a clockwise direction.

To find out what the current rules of the game are, examine the cards already played and determine which two of the following rules are active and which one is inactive:

1. Examine the serial number:

   1st SN	2nd SN	Previously-played suit
   		♠	♥	♣	♦
   Letter	Letter	♠ or ♥	♥ or ♣	♣ or ♦	♦ or ♠
   Letter	Number	♠ or ♦	♥ or ♠	♣ or ♥	♦ or ♣
   Number	Letter	♥ or ♣	♣ or ♦	♦ or ♠	♠ or ♥
   Number	Number	♦ or ♣	♠ or ♦	♥ or ♠	♣ or ♥

2. Ranks must alternate between being and not being:

   4th SN	Ranks
   0 3 6 9 C F I L O R U X	3, 6, 9, Q
   1 4 7 A D G J M P S V Y	4, 8, Q
   2 5 8 B E H K N Q T W Z	5, 10

3. 5th SN	Previously-played rank
   	A	2	3	4	5	6	7	8	9	10	J	Q	K
   0 3 6 9 C F I L O R U X	3 4 J Q	4 5 Q K	A 5 6 K	A 2 6 7	2 3 7 8	3 4 8 9	4 5 9 10	5 6 10 J	6 7 J Q	7 8 Q K	A 8 9 K	A 2 9 10	2 3 10 J
   1 4 7 A D G J M P S V Y	4 5 10 J	5 6 J Q	6 7 Q K	A 7 8 K	A 2 8 9	2 3 9 10	3 4 10 J	4 5 J Q	5 6 Q K	A 6 7 K	A 2 7 8	2 3 8 9	3 4 9 10
   2 5 8 B E H K N Q T W Z	5 6 9 10	6 7 10 J	7 8 J Q	8 9 Q K	A 9 10 K	A 2 10 J	2 3 J Q	3 4 Q K	A 4 5 K	A 2 5 6	2 3 6 7	3 4 7 8	4 5 8 9

Only one of the four cards in front of you is valid to play under the two active rules.
