Oh God, it grew to 12 (Inches). It was originally 9 (Inches) too. D=
Yeah, I had to pull the innuendo, lol. XD
NOTE: I do not bother to read the reviews of others. Forgive any repeats in case it occurs.
Geomancer: So, an interesting effect. Because it is treated as a Rock-Type monster in the Graveyard, it can cycle itself back when you use the second effect. Of course, since it is limited by a hard OPT, and probably would work best in a Rock deck, then there should be no fear of abuse. This card should be fine, but I'll take a second look at it after I finish the set. A valid target for E-Tele as well.
Pouncer: A Level 1 Rock-Type Tuner? Time to add that limited copy of One for One. The first Foolish Burial effect does have to be setting up something, and because it is archetype specific, and the second effect looks to be cycling your Rock-Types. Nothing wrong with this card either.
Crawler: Here we go. Now I'm starting to see where the combo is going with this card. Pouncer sends Crawler, and then Crawler adds another Rattler. Also, since the secondary effect can banish Pouncer, it gives you another add as well as a Level 2 Tuner on the field. Nice combo here.
-Gives Yuuji's thumb of approval-
Glider: Holy crap, another Tuner? Well, since you can splash more Rock support cards into this archetype, I guess it is to be expected. Great job for making a really generic Rock archetype though. The first effect is... Whew. I'm Imagining someone just dropping a Pot of the Forbidden with this effect, although Granmarg the Mega Monarch is the best choice. The second effect is more interesting, because you can sack it to have a monster attack directly. Used with Megarock Dragon, this card is very potent in conducting an OTK. Of course, all of this requires set-up, which gives your opponent a chance to fight back. This one is fine too.
Skimmer: Gasp. A Level 4 Rock-Type Tuner. Well, the first effect is handy as a hand trap in case your opponent activates something nasty. Pretty much a Forbidden Dress that you can play from the hand. It can also be useful in performing the combo with Glider for an OTK, because you can protect your monster in case they activate some sort of nasty effect to remove your monster. The second effect, of course, speeds up the engine and can be used with Crawler.
Lurker: Missing the stats, but can be very deadly. I presume you know about Ultimaya Tzolkin? This card could make summoning it very, very easily. Of course, Tzolkin sets up the Summon of Phantasmal Lord something... Stronger version of it. Trust me, that card is a jabroni, especially if you don't have removal set up or effect negation set up. I'm not sure about the reason you kept this card at a Tuner, but i suppose it can help getting out generics like Cloudcastle and Giganticastle. I'd look more into this card, because being a easy to Summon Dark Tuner that is Level 5 might cause problems.
Excavation: Oh boy, 2x Megarock Dragon at once with this card. Has to work specifically with a single card, but it can be expected as Geomancer is fairly easy to drop into the Graveyard. Then again, it can add itself after shuffling back into the deck, lol. The third effect is something special too, because giving all of your Rocks high level Kozmo non-targeting is quite powerful. No float effect, but that is to be expected for a card with various power effects.
Blessing: Pfft. Lol, it's a Foolish Banishment (Get it? Not funny? ;_;) that triggers a lot of the Rattler monster's effects. The second effect is rather powerful, and I think you should also put a hard OPT on it as well. After all, you can jump out a 2800 ATK beater if you managed to banish Mega Granmarg. Otherwise, it's a fine card, but the second effect is a little troubling. Maybe test this archetype out, and see what happens if you can maintain a 2800 on the field.
Rattler Call: Lol wut. Another archetype specific card, and acts as basically a E-Tele... Well, since this card is kind of the glue of the deck, I guess that is to be expected. It's certainly a unique archetype, lol. I'm pretty interested to see how they would function.
Rattler Mine: Ah, very smart to require a Rock-Type monster to activate this effect. Utilize Granmarg to pop the card, and then nuke all the S/T's on the field. Very, very likeable. The second effect is a little of concern, because there's no hard OPT on it like blessing. The thing is, because Black Rose Dragon is a viable generic synchro to use, you can nuke your opponent's field and have a large supply of Rocks to summon. (Mainly Granmarg or to perform another Synchro). However, because Mine is a Trap Card, this effect can also be resolved on your opponent's turn. I find this part to be a little worrying since you can keep Summoning a wall to protect yourself as long as you have banished rock monsters. Maybe Hard OPT it, maybe not, but it's all up to you.
Rattler Meteor: Oh... Well, the Summon requirement is pretty specific, but it really isn't hard to get out. Not only does it nuke everything, it also inflicts damage to both player. I'd only recommend the effect to be limited to Synchro Summoning, not whenever it gets Summoned though. This is because you can pretty much turn this card into a Wicked Eraser wipe with a simple COTH. The exciton effect might be a little too much, so maybe add an additional restriction. Remember how I said Mine can be resolved on your opponent's turn? It's a much OP version of Blaze Accelerator Reload when used in correspondance with this card.
Punisher: So, I'm guessing this card aims to Set every card on the field without targeting, making it a more OP version of Book of Moon. Again, I suggest limiting this effect by only being allowed to use it once, because whenever this card is Summoned, it can pretty much set everything on the field. That's a little troubling.
Note: Both Extra Deck cards are missing stats.
Overall, this archetype has a lot of potential, and is very interesting. A few errors here and there, but there's a lot of potential and creativity for this set.
Final rating: 8.5/10.
