Issyria, Sibyl of Dawn

Issyria is one of my personal favorite casters.  She is able to polish just about anything in the faction with her feat and has an excellent control debuff in blinding light.  Her spell list is basically all useful with a universal threat enhancer in Crusader's Call, an arm buff in Inviolable Resolve, the aforementioned blinding light, admonition, and a personal movement ability in velocity.  While she lacks any sort of personal damage most of our jacks can make solid use of ancillary attack.  My personal favorites are either colossal and the Banshee.

She is entirely capable of playing in pretty much all of our themes although Forges is usually going to lack the volume she wants.  Because most of Issyria's abilities are control wide she does an excellent job of buffing large quantities of models.  She is not overly survivable either so she typically wants to stay fairly far back behind her army.  At least one arc node is going to be typical for an Issyria list.

This is a swarm list I ran fairly effectively for several months.  I opted to put Eiryss3 on the infiltrators over the spears to push more models up the table faster.  Going first with this list (which gets a bonus to the roll from the theme) allows it to put tremendous early pressure on the table with Crusader's call on a mass high speed, pathfinder, advanced deploy models.  I'm partial to running double chimeras because I like having a throw away arc node.  I also like having a spare non stealth medium base to momentum over key models.

If you wanted to break the mass stealth the infiltrators could be replaced with Nyss hunters for a similar list and the chimeras could either both be replaced by Hemera or keep one and replace the other with a Siren or other light.  I personally keep the Banshee because I love the momentum assassination threat but running double heavy nodes with a phoenix and Hemera is also an option.

This is my obligatory double halb double AFG list.  With desperate pace and crusader's call halbs have a massive threat ranges and with Issyria's feat are very dangerous.  True sight AFGs are also quite potent.  I opted to go with lights in the battle group.  The extra ranged attacks from the harpies are very nice for her feat and they don't make terrible ancillary targets with solid range if you can maintain the AFG buff and a nice bonus effect.

I said Issyria was versatile so the third list is also in a third different theme.  This is the first list I've put up with a colossal.  Her feat is nice for fishing for that crit effect as you get to pick which die is dropped rather than being forced to drop low.  The main gun is also a very strong ancillary choice.  The arc node is again a flexible choice.  I went with Hemera in this list but I can see running just a chimera on Issyria and putting something like a siren on the Scyir.  I'm not a huge fan of the jack marshal bonus but it is an option and this list has a couple ways to speed it up.

So I promise I don't just always play double AFG (it's just a most of the time thing ;))  This list is more about leveraging the Vyre lights in conjunction with early threat from halbs.  Issyria doesn't do much to solve pathfinder so that can be an issue for a list like this.  I like stormfall archers with Issyria as she is able to help rat fix for them and on feat turn more dice is more better.
