"First attack one kill possible Infinite loop steel flame dragon" Deck 2020

Playing

Based on the movement of Dragon Link, we specialized in the realization of an infinite loop combo of 《Beelze of the Diabolic Dragons》's self-buff and 《Red-Eyes Flare Metal Dragon》's burn effect. If you have at least 3 types of starting hands, the first one kill will be established.
The success rate is probably about 1/7 to 1/8 if you go first and don't interfere.
*I posted the same content on the OCG database (www.db.yugioh-card.com/yugiohdb/). I will remove it if there is a problem.
The following is an example of deployment when 3 types of cards (+ 2 hand cost) of 《Black Metal Dragon》・Control Transfer Card ・Level 7 Special Summon cards are available.

Using her Rose Token on the opponent's field, transfer control of "Beelze of the Diabolic Dragons" with "Creature Swap" or "Mystic Box". turn end
Activate the effect of Blood Mefist during your opponent's Standby Phase. Triggered by burn damage, 《Beelze of the Diabolic Dragons》's self-strengthening and 《Red-Eyes Flare Metal Dragon》's burn effect loop
"It will be repeated 10 times or 20 times until the opponent's LP runs out due to damage."
The hand conditions are tighter, but you can get a one-turn kill even if you start with 《Chamber Dragonmaid》or 《Quick Launch》instead of 《Black Metal Dragon》.

Strength

Even if you can't kill it on the first turn, you can easily get to Borrelend Dragon if you don't interfere, so you can take your time and fight until you have all the combo parts (usually it's faster to win by punching normally, but...).
I also like the fact that there are no cards that will stop you from playing (as long as you can afford the hand cost).

Weakness

Very vulnerable to interference. No matter where the trigger is hit, the deployment will stop and it will be difficult to rebuild.

Customize

If 《Linkross》is banned, it will be difficult to secure a transfer method and a loop trigger when going first, but if you go second, you can hit 《Beelze of the Diabolic Dragons》from above with 《Borrelend Dragon》, so there is no effect. I think it's a good idea to give up the first one kill and increase the sense of stability.
