Flanking (Whenever a creature without flanking blocks this creature, the blocking creature gets -1/-1 until end of turn.)
Other creatures you control with flanking have flanking. (Each instance of flanking triggers separately.)
Cavalry Master adds only one instance of flanking per creature, even if that creature already has multiple instances of flanking.
If a creature without flanking is given flanking by another effect, then this ability will grant a second instance. Similarly, if a creature loses flanking, then it won’t get the Calvary Master instance either.
