"Barrel Dragon" + "Blowback Dragon" Once per turn: You can toss a coin 3 times and destroy as many monsters on the field as possible, but not more than the number of Heads.
How to Get
Able to toss 3 coins and destroy a number of monsters on the Field equivalent or less than the number of Heads.
Weak DEF stats.
Must be Fusion Summoned.
With more Fusion support released, this monster could be easily Special Summoned and its effects are devastating.
You can use Second Coin Toss continuous Spell to support Gatling Dragon’s coin-tossing effect.
If you Fusion Summoned using Barrel Dragon and Blow Back Dragon, you can use Gatling Dragon’s effect first, attack if possible, and then use DE-Fusion to return Gatling Dragon back to your Extra Deck and Special Summon Barrel Dragon and Blowback Dragon to the Field for more attacks.
You can use The Dark - Hex Sealed Fusion to replace either one of Barrel Dragon or Blowback Dragon as the fusion material. King of the Swamp also acts as the substitute Fusion material, and at the same time it can be used to search Polymerization from your Deck. Cybernetic Fusion Support allows you to pay half your LP and banish monsters from your Graveyard as Fusion materials (You still need to use Polymerization to Fusion Summon). Fusion Recycling Plant is able to search for Polymerization from your Deck, and it can recycle 1 Fusion Material to your Hand during your End Phase the Fusion summon was conducted. Fusion Sage is able to search for Polymerization from your Deck. Fusion Reserve allows you to retrieve 1 of the Fusion Materials from your Deck to your hand, and you can recover 1 Polymerization from your Graveyard to your Hand.
Master of Fusion Can be used each time your Life Points decrase by 1800. In the Draw Phase, instead of doing a normal draw, one Polymerization Spell Card, from outside of your Deck, is added to your hand.
Last Gamble Can be used in your Main Phase, starting from the fifth turn. Upon activation, reduces your LP to 100 and discards 2 cards from your hand. You roll a die and draw that number of cards. This skill can only be used once per Duel.
I think this card is good, not overpowered. Compared to other destruction cards, you'll most likely see this card on the field for one turn before it's destroyed by a stronger monster, and when you could use a stronger fusion, it doesn't seem that good except for a quick gamble
Stupid effect though on the part that if there are not enough monster cards on your opponents side of the field, the effect makes you destroy 1 or more of your own monsters and the card itself! Plus weak defense stats!
Lets be honest the chances of flipping 3 heads is quite rare on average you're most likely to get 2 and with all these meta types such as fur and sylvan which have the ability to summon 3 monsters in a single turn this card starts to look a little more promising so NO I wouldn't say it has a stupid effect I believe the term you're looking for is "useful" you can thank me later
We "know" like 10 cards from that pack. Odds are if Gatling Dragon is in here, Blowback's a SR or UR in the pack as well. Though you can use Substitutes for it, so, like Labyrinth Tank, they might just not release Blowback at all.
