Back to Opus V for this Rare card, not that rare, just a rare rarity.
On to the card
3CP/Fire
Job : Samurai
Category : XI
Forward
7000 Power
Rare
“Brave
If you have received 5 points of damage or more, Ayame gains +3000 power.”
Simple card.
Gets more powerful toward the end of the game, where Ayame gains 3K power just because you received 5 points of damage.
Tenzen is a no brainer. You will play Tenzen whenever you play with Samurais. You’ll most likely be grabbing an extra card at the end of each of your turns. But, that is a given. What else can we do with Ayame?
Look no further than Final Fantasy XI Volker (5-020R), Cornelia (6-007R) Iroha (8-004R) are all good ones if you ask me.
But, are you playing Mono-Fire? Are you playing Samurais? Or are you going to play a deck that focuses on the Damage you receive? Playing with your back against the wall, where the more Damage you received the more powerful your Forwards get. Cards like 
Morrow (11-013R) which will attack twice per turn at 3 Damage. Gabranth that gains +1K for each point of Damage you have.
And since we’re talking about Damage, Tifa (14-120H), cause everyone loves Tifa. And at Damage 6 you can play a category VII character on to the field. So, you might as well play Cloud (14-065L) and Barret (14-121L).
Fire/Earth is the way to go as you already have Gabranth, and FFVII in your hands. Don’t forget Lebreau (1-030R) for that +1K Power.
