Consuming Grudge is one of my favorite cards. I felt like making a topic about it.This is the card, if you haven't seen it.
It's especially good at activating these Soul Skills.Unknown Knight / AanoAwakened Magic Doll / EsriaMermaid AquamancerGuard Leader / RenallyRed Priestess / ColetteWhy is this card so good with multiple revival SSes?
This looks clunky at first glance because it's 3SP, but doesn't really cost 3SP, it only requires 3SP. If your units are units you would like to revive anyways, you would spend 1SP to do so. So if you are reviving 2 units with Consuming Grudge, you're really only losing 1SP in the grand scheme of things, and gaining additional copies of those units.
Multiple revival SSes are powerful gimmicks in their own right anyways. The opponent izcering into one is usually game-endingly terrible for them. They're usually not played because they are inconsistent and sometimes do nothing, but with Consuming Grudge they become more consistent.But wait! There's more! Consuming Grudge with Assassin SS
This does actually cost 3SP, but unless you're playing against Falkow it will guarantee your Assassin SS successfully goes off, due to the way -1LP skills work.
-1LP skills trigger soul skills before units close. This means, even if your assassin bait Shade is killed during the open phase, if you played Consuming Grudge you can still sacrifice it to your Assassin SS.
These aren't the only possible applications for this card, but I think they're the most powerful, and if you're thinking of playing this card, this is where I would start.
Rapidly Flying Apprentice's Kill Count: 14 Izcers.
