Macro Help

So ive been trying to make a macro that will use soul barrier when its not on cooldown but will cast soul Cleave when it is on cooldown.

I was told about Gnome sequencer so i downloaded it think i would be able to make the macro but so far im confused and would like some help if anyone can help me with this.

well gnome Sequence is more of a rotational macro builder. if you really want to make a macro of only 2 spells you should use Macro toolkit it will tell you if the macro you are trying to build will work and if not where the error is.
