• This card came out in the 2nd set, Metal Raiders.
• It was one of the first few LV5+ monsters with an effect.
• This card has weak stats, but it's effect has made up for it.
• This card was useful in the Chaos era to dump a LIGHT monster into the graveyard quickly.

• The effect is a +1, because you get 2 cards for the price of one.
• Most decks shouldn't use this card because the two cards you get are basically filler.
• When Graceful Charity was legal, it was easier to use this card for a discard.
• Otherwise, decks needed to use somewhat risky cards like Raigeki Break and such.
• This card does thin the deck, increasing your probability of drawing cards you want to draw.

• The big downside of this card is that if you open the game with 2 of them, instead of being a +1, it's a -2.
• This card has always had potential niche uses, but overall (especially at the moment), it isn't great.
• But in the future, it's possible there will be a deck to utilize this card.

Hello Pojo Fans,
 
Thunder Dragon should be called “Discard Fodder” instead.
 
Easy to use: ditch one to get up to 2 more “Thunder Dragon” from your deck. It's a +1 and thins your deck, and if you are using a lot of resources for discarding, playing a set of this monster may be a good idea. They are LIGHT so they are Chaos fodder, but not much else help in terms of being a good monster besides being discarded almost immediately. I can't even imagine having this and Graceful Charity back in the day to start off the game, it must have felt like Christmas. With Pendulum monsters front and center, Thunder Dragon could be Pendulum Summoned and used to go Rank 5, but its best use is as being removal and discard fuel. Had it been a Dragon-Type it would be even better.

We follow up an old card with an even older card. Thunder Dragon is a Level 5 Light Thunder-type monster with 1600 Atk and 1500 Def. Those stats are awful for a Level 5 monster. Those stats would only be ok on a Level 4 monster. The effect isn't great either. Thunder Dragon can discard itself to search up to two Thunder Dragon from the Deck to the hand. The fusion of these cards is not great. There is no good draw card associated with having Level 5 Light Thunder-type monsters in the hand. At best, the other two could be discard costs and deck thinners. There are much better options out there. 
 
Score: 2/5 for the 2 cards you end up with. Don't draw more than one of these. 
Art: 4/5 This and Grapha make me wish for some dual typing.

Thunder Dragon

There is no current or foreseeable use for this monster outside of FTK decks which uses it to thin out the deck and then provide material for discard costs. It’s pretty much garbage and will probably never see the light of day again unless, by some miracle, a good card comes along that needs to discard two thunder types to activate. That’s probably never going to happen.
