w-summon, knights of the round and mime.
and for emerald last resort and phoenix aswell.

Please stop making new threads all the time. Just post in your current FF7 threads (pick one).

With Ruby, it helps to have two characters dead when you start the battle. Or else they will be removed from the battle completely. Then you can revive them in battle with the Phoenix summon.
