(Concluding with a rock ballad from one of my favorite Finnish goth bands)

A decent 2400-ATK beater which can provide an out to a number of powerful monsters.  You're spending 2 cards on a Beast of Talwar and a Smashing Ground (or Hammer Shot) to be precise.  There's better and even easier to use removal options out there, but it can be helpful in certain situations.  The restrictions of the effect working only once and only if it's Synchro Summoned hinder it more than they prevent abuse.  Not a bad card when all's said and done.  Just not noteworthy either.

2/5

Not technically a member of the Red Dragon Archfiend family but still a Red Dragon Synchro Monster.  Level 6 Synchro, 2400 attack and 1500 defense, and Synchro Summoned with a Tuner and one or more non-Tuner Monsters, so it's simple enough from the onset.  So once a turn during either players' turn, you can destroy a Synchro Summoned card with the highest attack.  Fantastic, except you're not very likely to run into a Synchro Monster which makes that pretty moot in the current environment.  Said effect can only be used once while this card is face-up on the Field.  He's not bad, just that effect won't get used much.  If Synchros start coming back into the game, I'd use him.  He's quick, strong enough for his Level, and well supported being a Dragon.

Red week concludes with one of the lesser impressive cards, Red Wyvern. There are better Level 6 Synchro monsters to Special Summon than this monster. Standard ATK for a Level 6 leaves it lacking compared to Goyo Guardian. Destroying a higher ATK monster your opponent controls, good, ability to do it on either turn, great. The  problem lies within its restriction. A one-time kill isn't good enough. Only being able to use the effect if Wyvern was Synchro Summoned lowers the playability more. After the effect is used, this card becomes a defenseless 2400ATK monster.
 
There's better Level 6 Synchro monsters to use. Use them instead.

Red Wyvern. Even the name disappoints me. It should be Red Wyvern Archfiend, or something. It's ok but it is not the combo starter that I wished/thought it was going to be. I blame the stats. Red Wyvern is a Level 6 Fire Dragon-type Synchro Monster with 2400 Atk and 2000 Def. Normally, that would be good enough for a good score. But since it is Fire instead of Dark it becomes useless as an option for the new Hot RDAs that came out. Furthermore, The name not including RDA means that it is not a target for some of the Hot RDAs' effects. 
 
There is a good effect on Red Wyvern, but you can only use it once while it is Face-up on your side of the field. You can use it during either player's turn, but unless I can somehow summon this consistently during the opponent's turn, I'd rather have been able to do it once per turn and only on my turn. Anyway, the effect is basically just a single target boss killer. After Red Wyvern is Synchro Summoned if there is a monster with higher Atk than this card on the field, you can target the highest Atk target and destroy it. I am glad that there is no cost, but there are way easier ways to get rid of a big monster. You don't even get to pick which monster to destroy if there are multiple monsters with greater than Red Wyvern's Atk. I would score it higher if I could at least use it after a Soul Charge or Call of the Haunted, but it is after Synchro Summon only. Just meh. Great looking meh. 
 
Score: 2/5 Why did this have to be Fire?
Art: 5/5 I still love how it looks.
