I feel somewhat obligated to post this; a multisphere true god church file I made that utilizes Galderia's SS. Around set 9 it reached 2000rp and remains very competitive. Although actual multisphere TGC cards have been released since then there simply is no room to work them in. In fact several key units are already limited to only two copies, but that is made up for by revival grims and the general tankishness of the file.

This file will always open: (lawtia level 1) MD Defective > Shade (> Shade). Whether you play the second Shade should depend on the risk that the next unit you set could be hit by your Assassin SS. Next you should almost always set Anatilla. Once she's on the field you have several open skill you can use to defend her for that first turn, either Church Paladin, Priests of the Royal Guard, Fortune, Return, or Cyclone. Church Paladin is usually your best choice, but Priests of the Royal Guard can be hand when you don't have enough SP to play him and use Anatilla's action skill. If you are forced to use Priests of the Royal Guard its generally best to set Church Paladin next turn. Fortune has a powerful open skill but you shouldn't waste it on anything less than a level 4 or a level 3 undead. Cyclone is excellent for solidifying your advantage, don't be afraid to use it to return just 3 or 4 SP worth of units, you'll quickly make up the difference. After setting Fortune or Church Paladin you want to get out Gilensia next, of course its ok to let Church Paladin close and revive once to do this.If it safe, Raste is the next card you should put down, Bardia can be used to put Gilensia out of the range of 40DMG SS. I think that's all I have to say about order. Bardia's start skill can become very power full in this file, eventually you should be using it as your buff for Church Paladin and Gilensia's Start Skill on Bardia after Raste has boosted his Max HP. You may have noticed the synergy between EX:Yuni, Church Paladin, and Priests of the Royal Guard (EX:Yuni is royalty so Church Paladin's Open Skill will give everything a temporary 30ATK buff) but generally you should be getting Church Paladin out too early to make use of it. EX:Yuni is mostly useful for slowing down Gilensia so his Start Skill goes off after Raste's and he can revive units after the last of your enemies attack, and for her action skill which is rendered inexpensive by your massive early SP gen and deadly by your large and enduring field.I think that's all I have to say, if you have any questions ask me. This file has an answer for just about everything if you know where to find it.
