New pg vs Old pg

[Pinkie_Pie]

Old pg -Card Effect(s)
[CONT]: Sentinel (You may only have up to four cards with "[CONT]: Sentinel" in a deck)
[AUTO]:[Choose a card from your hand, and discard it] When this unit is placed on (GC), you may pay the cost. If you do, choose one of your units that is being attacked, and that unit cannot be hit until end of that battle.

New Pg-
[CONT]: Sentinel (You may only have up to four cards with "[CONT]: Sentinel" in a deck)
[AUTO]:[Choose a card from your hand, and discard it] When this unit is placed on (GC) from hand, you may pay the cost. If you do, choose one of your vanguards that is being attacked, and that unit cannot be hit until end of that battle. Then, if you have a card named "(A copy of this card)" in your drop zone, choose a card from your damage zone, and turn it face up.

Ok so the big diference from the new to the old is that you cant guard rearguards with the new one but with the new one can unflip damage as long as when you use it you have a copy of that card in the dmg zone.
Old pg pros - they can guard anything and you dont have to have to play 4 of them  cons -is that they dont allow you to unflip anything like the new ones.
New pgs pros -The only pro is being able to unflip that will happen in average 1 to 2 times for game cons- you have to play 4 of them so you can have more chances to unflip damage, they cant guard rearguards and they are useless in decks that dont use a lot of counterblast.
New pg also sucks agains some matchups like the dotx and d robos agains dotx your opp can hit a rg because you cant pg that you need to guard with tons of guard or just let the attack go you gonna end up with a rg retire and your opp just make a +3 or more if he haves dotx in hand and if you defend the vg next a +4 and 3 rgs retire , agains robos and ty to laurel and stride your opp can hit you a rg and he will drive cheak 6 times.
So what is the point on new pgs? i prefer my reliable old pg

They shoulda just made the new pg's have the unflipping skills/able to work on RG's as well.

[Pinkie_Pie]

If they do that the new pg would totaly replace the old one this way you can pick the pg that you want (even if the new pg is bad and people dont see it)

At the end of the day it's really a preference if you want to run the newer or older perfect guards. If your deck is counterblast heavy then you might prefer to run the new perfect guard even knowing the risk of using it. If your deck doesn't use a lot of counterblast and/or you know your deck can manage unfliping all the damage back consistently then you might be able to get away with using classic perfect guards.

[Agame]

Well when it comes to reality the new pf are the best (in my opinion).pf unflipping regardless of how counter heavy u may be are the best.
But know i realize that you could only guard the vng old pfs are better for some decks

[Lequier]

The new Perfect Guard vs old Perfect Guard theory is actually purely meta-call reliant. In a format such as the one that the JCG is currently in where DOTX is considered to be the deck to beat, the best kind of PG is going to be one that can guard against rearguards due to The End being able to restand if it hits against a rearguard. Otherwise, a lot of guard would have been forced onto the rearguard unless you are going to take the hit and let your opponent gradually overwhelm you with masses of advantage. The same argument can also be said for any meta relevant Dimension Police decks that occur in the future due to Laurel being able to resolve if it hits vs a Rearguard.

I actually think that if you dont need QW, then you need to rush new pgs, if you're able. Defending rgs is not that important - only 1 clan can excel at it - Dimensional Robo, and they are not meta to build deck against them. The X, if he is attacking your rg are getting +1 card in the hand, and +2 checks - so his chances to get triggers are higher. But if you have this PG in your hand, he wont be able to finish you anyway. Btw he get this +1 card for 2 cb, wich is preety expensive, while OTT gets 1 card per 1 cb, and have choice. So I dont think X is a problem with new PGs. Only Dimensional Robo - but since Daikaiser they love to play with enemies PGs Maybe even earlier...

You realise that letting the X restand will basically able to kill of 3 of your rears. That is the main point of it. To cover up the losses of twin drive by swinging the end into the rear first. I would not let them re-stand.

The new PG is not that heavily needed. Clans like Royals and Nectars benefit of the most because they are able to replace their field without much pressure.

If the X/ End restands, it can also stack up triggers either to vg or rg, plus it gets to replace the 2 g3s ( the x and the end ) with 4 drive checks and 3 of your dead rear guards. I actually prefer old pg in my decks just because of the x and stride laurel unless it is absolutely necessary to run new pg ( such as in OTT ).

[Rank Up]

well, lets dig some deeper. Every turn, since you are using g3 to atack, you get minimum 3 cards per turn. Today's most standart retire price is 1 cb per unit (try to not think about nuckle), same goes to bonus draws - 1 cb per card. So basically we have a situation, when the X is attacking rg. I'd let this attack pass, so he checks 2 cards, that he would check no matter what + retiring one of my rgs in front row, maybe getting triggers whatever. Then he drops 1 card from hand, paying 2 cbs and stands. So at this moment he lost 1 card from him hand and 2 cbs, we lost an rg. Then he attacks again, but this tame target is vg. We are using PG, probably unflipping one damage. He checks another 2 cards - now he have minimum 4 cards, that he got this turn. Then he drops one more card and pays 1 cb to retire to of my units. So this turn he gets 3 cards, as he would get anyway, and lost 3 cb on retiring my 3 rgs. The only thing that is beyond that is that he had more chances to get a trigger (perhaps instead of 13% chance he got 26% or something like that). Is this really the thing you will not take new pgs for? I dont think it's worth it. All this legion do is basically retire 3 pgs on fixed price, while doubling his trigger chance. And this legion need special cards in his hand. I bet you will say that X is searching for needed card himself, but realistically, your opponent can see this card and decide will he let this attack go or not.
When comparing this legion to any kagero stride, I see that, kagero strides get +3 card per turn, with higher chance of trigger (though less, then The End), and retiring 0 to 2 of your card COMPLITELY FREE. I dont even mention, that they have higher base power, which is harder to def against without PG. Also there is always a possibility that you wont get the X in vg circle in this build, and then you'll be forced to play The END, which will attack with power 16-18 trying to get a restand. And even if he'll attack rg, you can just throw 2 triggers at him, saying: "Nope!" - and be happy.
