First off, I'd like to note that if anyone disagree's with these following opinions, they are well-entitled to their own xD.
Second, I'd like to note that after severe scrutiny of Galactic overlord's cards, I feel entitled to note that I was not overtly impressed with any of the cards.
There were effects that interested me, but nothing stood out overall except 1 card. However, I have decided on the four other cards that I consider worth taking a look at.
TardyOrc - I'd like to make it clear that I am not a big fan of this card overall, I've never been a big fan of the penalized lower level monsters like Goblin attack force and Giant Orc, however I cannot deny that they are useful in their own ways. Breaking it down, Tardy Orc is a lvl 4 monster with 2200 atk and 0 defense, much like it's brethren, however unlike the others, it is not changed to defense mode after it attacks which is definitely a bonus, it's limitation is simply that it cannot attack the turn it's normal summoned, this hardly matters if it was summoned on the first turn. (Slightly off topic but perhaps relating later: I have noticed that with changes to the game, the basics that people clung to in the past have changed somewhat. During most of my time dueling, if you were going first, a very common move was to set a monster and generally a single trap or even a spell and end. Why? Because it made you feel safe, a set monster meant you would take no damage against the threats your opponent tossed out and a hidden trap or bluff spell made your opponent feel uneasy and hesitant. With Cards like Dark World Lightning, Night Beam and other cards, this is no longer the truth, your field is exposed instantly and you left open to massive damage due to so many cards that your opponent could have built their deck with, in a moment you are swarmed and it's a one turn kill and you are left feeling confused and ashamed. So now, people play aggressively, tossing out as much as they can to prevent your turn from meaning much, not that they can't be wiped out, it just might take a little more effort or...less depending xD.) Anyway, TardyOrc's power lies in just that, his attack points, a 2200 beat stick that your opponent will want to get rid of. Not saying it's a great plan, but if they waste a combo killing it, your bigger friends might come out, and playing him on turn one puts you up not just a heavy hitter, but a good blocker, you won't take nearly as much lp damage as you may have otherwise. All hypothesized of course. Besides that, he's pretty much fodder for Allure of Darkness
Black Luster Soldier EOE and Chaos Sorcerer.
Against Current Metagame: Not too much capability besides being a beat stick. Easily Splashable in most decks
Cardcar D - Okay, I don't like the look of this card, I think it's a silly car and it's main goal is apparently to come out of the gate, crash into a wall and get taken to the scrap yard but, thankfully you had insurance and that wall wasn't supposed to be there, so you get your money back plus a little more. This card is alot slower now though and if you are not careful, it's no more useful than a Hotwheel's toy.
I like any card that even's out, Jar of Greed 1 for 1, Moray of Greed 3 for 3, Pot of Duality 1 for 1+ you get to pick. So of course, this card is obviously useful, why? Because it's 1 for 2. That silly little Pontiac just became a Camaro and a Mustang, potentially more (Too much Car shpill?). Any card that replaces itself is good, a card that does more than that is wonderful. However, with priority being sent off like the bad little child it was, it's not as good as it could have been, well I say that But then you look at the darn rabbit and realize, it's still a pain in the unmentionables D<. While it can't be special summoned, you can always get it back with Monster Reincarnation and it's ilk (Course, I hope you are giving up something reasonable to make that move).
Against Current Metagame:Easily splashable in most decks, Card advantage +1, nothing really specific, but isn't that what makes them grand? XD
Nightbeam - Well, I see no overall negative to this card, it does what it's made to do, pick a target and take it out without any resistance, a sniper taking aim and firing pretty much. It's no mystical space typhoon that's for sure but sometimes it's nice to know you can take out your mark without it turning into a bomb that blows up in your face (No sense for a sniper D<). There are many cards that you want to destroy that your opponent may be waiting to activate until they know how things are going to go down. However when comparing it to the typhoon I give this card....a 5....out of 10. (End Credits.)
Against Current Metagame: As noted, nothing specific and that's what makes it grand, Dark deal hates it though. Easy to splash
Dimension Slice - Without a doubt, this is one of my favorite cards in the entire set, it's very easy to use as special summons are so common now and banishing is one
of the few ways to get rid of some of these reoccurring headaches, not that they can't come back. Not to mention you can activate it the turn you set it if you special summon an xyz, which, from what I can tell is pretty damn easy, so that means it's less likely to be destroyed....Compared to other cards. You annoyed by a monster that can't be destroyed? No problem, Grapha keep coming back? Not anymore! In some cases, this leaves you an open field to attack with a potentially powerful monster. I love you Dimension slice (When everyone special summons... Are they really special anymore?).
Against Current Metagame: Great Card against some Dark World Tyrants or at the very least, no worse than some others. Easy to splash in almost all decks.
Okay, I was kind of Torn on this last card, I wanted to avoid Hieratics and Evol's when I made this, something that doesn't rely soley on it's archetype. This card has
some benefits but...Not surprising, I don't care too much for it.
Photon Bouncer- FIRST and most important to note... THIS IS A RANK 6 Xyz monster, that might not sound like much to discredit this card to some of you, but
I promise you, this will be much more difficult to get out there then your casual 3's and 4's. On a side note, it's a pretty good card once out, with a 2700 atk points
it's a heavy hitter for most. Next, It's effect... This monster prevents the activation of effects and burns the opponent for it, it's limited to once per turn and two times only, unless you mix in some XYZ rebirth, Overlay regenerate and other cards. I think there are plenty of other cards that can help with that matter better than this card. However, you may have been able to prevent that sneaky rabbit from causing trouble, or maybe a newly summoned inzector, it's like telling a child no, he'll get it at first, but he'll probably try it again. Besides that, it's a light monster, lots of support for that.
Against Current Metagame: Has it's uses, not easy to splash in place of most cards, but your opponent will be alot more careful with their turn if he's saying hi.
Well, that's my Opinion anyway....
