Koa'ki Meiru Rooklord

Koa'ki Meiru Rooklord

It's like the Monarch of the Koa'ki Meirus, except that it's a +1 when used as intended or a +2 when used with Mausoleum of the Emperor. As for its side-effect (revealing a Warrior in your End Phase), it's not that bad. Warriors aren't hard to come by.

It could be used in some deck that abuses Mausoleum of the Emperor (Light and Darkness Dragon?), but I'm thinking some sort of Koa'ki Meiru/Monarch hybrid. Koa'ki Meirus have some decent Special Summon support and it could work. Maybe a build with Guardian, Boulder, and Granmarg? What is troubling is somehow being able to get a Koa'ki Meiru to tribute for Rooklord while having a Warrior in your hand. Obviously, when you tribute a Koa'ki Meiru for Rooklord, there'll be one in the Graveyard (the one you tributed), normally.

Still, having a Warrior in your hand when you need it could be difficult. Possibly another Rooklord? I can't think of many Warriors that would work in the deck, besides Kuraz, which is bad. Marauding Captain? Necro Gardna? Vengeful Shinobi? Maybe some sort of Hero? They're searchable and decent. However, they have no real synergy with Koa'ki Meirus or Monarchs.

Why not just tune something to Rooklord after summoning it? Emergency Teleport and One for One provide the Tuner. That would be super situational, though.

Why did they have to make the Koa'ki Meirus so bad? They actually seem cool, but the way they work, they're not a viable deck type. They can barely be splashed into other decks! Rooklord and Guardian are probably the only Koa'ki Meirus that I would play, and I can't play them!
